It is 2am and you are googling whether the ache in your right trap is normal or whether the therapist did something wrong. The massage was on Saturday. It felt good at the time. You slept fine that night. Then Sunday afternoon your shoulder started to feel like you had done a heavy gym session, except all you did was lie on a table for an hour, and now you are lying awake wondering whether to book again or write it off as a mistake.
This is one of the most common questions in massage, and it almost never gets a straight answer. Some soreness after a session is normal, sometimes even a good sign. Some is a signal that something was off. The difference between the two is what this article is about, and by the end of it you will know which one you are dealing with tonight.
Why massage can leave you sore in the first place
A massage moves muscles that spend most of their time doing very little. If you sit at a desk in Westminster for eight hours a day, your upper traps and rhomboids have been holding your shoulders in roughly the same position for weeks. When a therapist works into that tissue with sustained pressure, they are pushing fresh blood into muscle fibres that had adapted to being still. The result feels similar to the day after an unfamiliar workout.
Cleveland Clinic massage therapist Victoria Bodner explains it plainly. Massage forces blood into the muscles and brings in nutrients. The process can temporarily increase inflammation in areas the body feels need attention. That inflammation is the same mechanism that causes delayed onset muscle soreness after exercise, which is why the ache feels familiar even if you cannot remember doing anything to cause it.
Improved circulation is the underlying reason massage works at all, and it is also the reason for the soreness in the first 48 hours. You can read more about how massage improves circulation and why that shift in blood flow produces both the immediate benefits and the short-term aches.
There are four common reasons the soreness shows up.
- Your muscles were holding more tension than you realised, and the therapist worked into it directly
- The pressure was deep, particularly if it was a deep tissue or sports massage rather than Swedish
- You are new to massage, or it has been months since your last one, so your body has no recent memory of being manipulated this way
- You were dehydrated going in, which makes muscle tissue less responsive and more prone to post-session inflammation
All four of these produce the same physical result. Ache, mild stiffness, sometimes a bit of tenderness where the pressure was most concentrated. It should feel more like the day after a workout than like an injury.
The difference between good soreness and something is wrong
Normal post-massage soreness has a specific character. It is a dull, generalised ache in the area that was worked on. It feels roughly the same as the day after an unfamiliar workout. It is worse when you first move in the morning and eases as you warm up through the day. It does not have a sharp edge to it. It does not restrict your movement in a way that stops you doing normal things.
It should also have a timeline. Most soreness starts settling within 24 to 48 hours and is gone by the third day at the latest. If it is easing steadily, even if it is still there on day two, that is a normal recovery pattern.
Concerning pain looks and feels different. Watch for any of these.
- Sharp, stabbing, or shooting pain rather than a dull ache
- Pain that gets worse over the days after the session rather than easing
- Numbness, tingling, or pins and needles in the area, or radiating down an arm or leg
- Bruising that is extensive or that appeared without heavy pressure being applied
- Pain that stops you sleeping, driving, or working normally
- Soreness still present five or more days after the session
Any of the above warrants a call to your GP, not another massage. A qualified therapist would tell you the same thing. Pain that behaves like an injury needs to be assessed as one, not massaged again in the hope that it settles.
The 2am test is straightforward. If the ache feels like sore muscles after exercise, and it is easing rather than worsening, you are in normal territory. If it feels sharp, is getting worse, or is stopping you from moving properly, that is a different conversation and it is not one to have with Google in the middle of the night.
What to do in the first 48 hours to help the soreness settle
The good news is that normal post-massage soreness responds well to fairly simple aftercare. None of this requires a pharmacy trip or a complicated recovery routine. It is mostly about giving your body the conditions it needs to clear the inflammation and rebuild the tissue that was worked on.
Hydration is the single most useful thing you can do. Drink water steadily through the rest of the day of your massage and the following day. Not litres in one go, just consistent sips. Well-hydrated muscle tissue clears inflammation more efficiently than dehydrated tissue, which is why the soreness is often worse in people who arrive at their session already dehydrated.
Move gently rather than resting completely. A short walk, ten minutes of light stretching, or a slow swim helps the muscles clear the metabolic waste that has built up. Total rest allows the tissue to stiffen, which makes the soreness feel worse the next morning. Save the heavy workout for 48 hours later.
Heat is the next step for the average person. A warm bath, a shower with the water directed at the sore area, or a hot water bottle for 15 to 20 minutes at a time all encourage blood flow into the tissue and speed up recovery. If the area feels genuinely inflamed or slightly bruised, cold works better than heat for the first few hours, then heat once the acute stage passes.
Sleep is where most of the recovery actually happens. Your body does the majority of its tissue repair overnight, so a proper night's sleep after a massage matters more than any supplement or cream. If the soreness is disturbing your sleep, that is worth noting, because normal soreness should not be intense enough to keep you awake.
What to avoid in the first 24 hours: heavy exercise, alcohol, and long periods of sitting still. All three slow the body's ability to clear inflammation and lengthen the soreness rather than shortening it.
If your massage was a Swedish massage rather than deep tissue, the soreness should be lighter and shorter. Anything more than mild aching after a genuine Swedish session usually points to a pressure mismatch, which is a separate issue and worth flagging with the therapist before you book again.
A Camden client who nearly did not book a second session
A woman in her late thirties working in publishing near Camden Town had booked her first proper deep tissue massage on a Friday evening. Her shoulders had been building tension for months, sitting at a laptop from home three days a week and in the office two. The session itself was good. The therapist was clearly qualified, the pressure felt intense but productive, and she left feeling looser than she had in weeks.
Saturday morning she was fine. Saturday afternoon her right shoulder started to ache. By Sunday morning it felt worse, and she was convinced the therapist had done something wrong. She spent Sunday afternoon on her phone weighing up whether to email and complain, whether to write a bad review, or whether to just quietly not book again.
What actually happened was straightforward. The therapist had worked into an area that had been holding tension for so long her body had adapted to the tightness as its normal state. Releasing that much sustained tension in a single session produced exactly the delayed onset soreness this article describes. It was normal. It was even a sign the session had reached the tissue that needed attention.
She messaged the therapist on Monday to ask whether the ache was expected. The therapist replied within an hour with the explanation, suggested a warm bath and gentle stretching, and confirmed the soreness would settle by Wednesday. It did. She rebooked for two weeks later. The second session produced almost no soreness at all, because her body had adjusted to being worked on.
If she had cancelled the second booking on Sunday afternoon based on the soreness alone, she would have lost the therapist who eventually resolved the tension that had been there for a year. The message she nearly did not send was the thing that kept the treatment on track.
When the soreness was not your body, it was the therapist
Not all post-massage soreness is normal. Some of it is the direct result of a therapist who was working outside their competence, ignoring feedback, or applying pressure that was wrong for the body in front of them. This is uncomfortable to say plainly, but it matters, because a reader who blames themselves for pain caused by a poor session is a reader who stops booking altogether.
These are the signs the soreness came from the therapist rather than from your body's normal adjustment.
- You told the therapist the pressure was too much and they did not adjust
- Bruising appeared in places where you did not ask for deep pressure to be applied
- The therapist did not run an intake or ask about medical history before the session
- You felt genuine pain during the session rather than intensity, and you were not encouraged to speak up
- The soreness came from an area the therapist worked on despite you asking them not to
A qualified therapist matches pressure to the body they are treating. They check in during the session. They adjust in response to feedback. If your soreness came from a session where none of that happened, the issue is not that your body reacted badly. The issue is that the treatment was not delivered to a professional standard.
The next step is finding a therapist whose approach suits you before the next booking, rather than after it. That means reading the profile properly, checking that they are registered with a professional body, and looking for language that suggests they understand pressure adjustment as a core part of their work rather than an afterthought.
You can browse verified independent massage therapists across London and filter by treatment type, area, and availability. Every listing is checked before it goes live, which removes the first layer of guesswork. From there, look for therapists who name specific specialisms, describe their approach in the first person, and make clear that pressure is adjusted throughout the session rather than fixed at the start.
If your last massage left you sorer than it should have, the answer is not to give up on massage. It is to find someone better matched to what your body actually needs. Explore trusted independent therapists near you on I Love Massage UK and make the next booking the one that works.
Frequently asked questions
Why am I still sore three days after a massage?
Soreness lasting into a third day is at the outer edge of normal, particularly after a first deep tissue session or after a long gap between massages. If the ache is dull and easing rather than sharp and worsening, it is still within a healthy recovery pattern. Soreness that is still intense on day three or has not started reducing at all is worth flagging to your GP.
Is bruising after a massage normal or a sign the pressure was too hard?
Small, faint bruising in areas that received deep pressure is not unusual, particularly if you bruise easily generally. Extensive bruising, bruises in places where deep pressure was not requested, or bruising accompanied by significant pain suggests the pressure was too heavy for your body. That is a pressure mismatch, not a normal response, and worth raising with the therapist before booking again.
How long after a massage should soreness fully go away?
Most post-massage soreness resolves within 24 to 48 hours. Some deeper work can leave mild aching for up to 72 hours, particularly in areas that were carrying significant tension. Soreness that is still present after five days, or that is worsening rather than easing at any point, is outside the normal range and needs medical assessment.
What should I tell my therapist about soreness from the last session?
Tell them exactly where the soreness was, how long it lasted, and whether it felt like a dull ache or something sharper. That information helps them calibrate pressure for the next session. A good therapist will use it to adjust their approach, not defend the previous session, which is one of the clearest markers of professional practice.
Why do I feel more tired than sore after a massage?
Deep relaxation of the nervous system produces a noticeable drop in energy for several hours after a session, sometimes into the following day. This is your parasympathetic system fully engaging, which is generally a sign the massage worked. Rest into it rather than pushing through, and drink water regularly across the following 24 hours.
