After treatment — what to expect, what is uncertain, and what to ask
Most of what is written about this subject is written by people selling it. That shows up most clearly in the questions patients actually ask afterwards — whether it hurts, how long it takes, how long it lasts — where the honest answer is rarely the reassuring one.
This page answers those questions in general terms. It is not instructions for your own care, and it cannot be: what applies to you depends on what you received, where, and from whom. If you have already been treated, the person who can answer these questions is the physician who treated you.
The answers below are the treating physician’s own. For what the published evidence shows — including the risks, disadvantages and documented harm on record — that is a separate page, and a longer one.
Is it painful?
What you can reasonably expect. For an injection into a joint, expect discomfort from the injection itself and some soreness around the treated joint afterwards. For an intravenous infusion, the experience is generally different: the main procedural discomfort is usually related to obtaining venous access rather than to the infusion itself.
What is uncertain. The intensity varies considerably between patients and procedures. The physician’s words: “I would not describe it as either painless or necessarily severe.”
What to ask. Before treatment, ask the treating physician what is expected for your specific procedure, what symptoms warrant contacting the team, and what should prompt urgent evaluation.
What should you not do afterwards?
What you can reasonably expect. Before you leave, you should know what activity restrictions apply, whether medications should be continued or avoided, when normal activity can resume, when follow-up is expected, and whom to contact if something changes.
What is uncertain — and why there is no list here. We deliberately do not publish a general list of restrictions. The physician’s reason:
That search term groups together very different procedures, routes of administration, anatomical sites and patients. Instructions that are reasonable after a knee injection are not necessarily the instructions I would give after an intravenous treatment.
You will find lists elsewhere. They disagree with each other, and they are not labelled with which procedure they describe.
What to ask. Ask for those five things specifically, before you leave, and ask whom to call. For patients treated through this process, the specific instructions come from the clinical team according to the actual procedure.
How long before you would know whether it worked?
What you can reasonably expect. For joint treatment, do not expect an immediate result. Changes in pain and function, when they occur, are generally assessed over weeks rather than hours or days, and improvement may continue to evolve over subsequent months.
What is uncertain. Not every patient improves. And the absence of an early change does not by itself establish whether the treatment ultimately helped. We also do not publish a day or a week at which treatment is declared a failure — that judgment depends on the procedure, the condition and the patient.
What to ask. Agree with the physician in advance on what outcome you are trying to improve, and when it will be reassessed. Pain, function, and the ability to perform normal activities are far more useful than asking yourself “do I feel better yet?”
This answer is about joint treatment. Cancer, immune and wound cases are assessed differently, and on different timescales — what is being measured is not the same thing. Those specifics live on the page for your care path.
How long does it last?
What you can reasonably expect — and the question needs taking apart first. There is no single clinically meaningful answer, because the question means several different things at once: how long administered cells remain detectable, how long a biological effect persists, and how long a patient experiences improvement. Those are not equivalent questions, and a single number cannot answer all three.
What is uncertain. This one, more than any other on this page. We cannot promise that a benefit will occur or, if it does, exactly how long it will last. The physician declined to give a figure, and gave his reason:
Do not invent a simple number because the question invites one.
You will find specific durations published elsewhere. They range from months to several years and they do not agree with one another.
What to ask. This is the section where the question matters most, and the physician’s own formulation is the one to use:
How will we decide whether this worked for me, when will we reassess it, and what happens if the benefit is absent or later decreases?
A clinic should be able to answer that even when it cannot promise duration. If it cannot answer it, that is information about the clinic.
If something seems wrong afterwards
Contact the clinical team that treated you. That is what they are for, and concerns after a procedure are a normal reason to call.
Seek urgent medical attention for warning signs such as fever, spreading redness, rapid deterioration, or a limb that becomes acutely cold, pale or painful.
And what this page will not do: tell you whether a symptom you are having is normal. We have not examined you and we did not perform your procedure. That judgment belongs to the physician treating you — and any website willing to make it for you is telling you something it cannot know.
What to ask before you agree to anything
These are the treating physician’s questions, and they apply anywhere — with us or with anyone else:
- What result are we realistically trying to achieve? Less pain, better function, wound closure, immune recovery, something else. You should know what success would actually look like.
- What are the known risks and uncertainties?
- How many procedures or visits are expected? And what happens if additional treatment is suggested later?
The full set of twelve is on the costs page, together with what makes prices so difficult to compare.
