Relaxation, tiredness, a possible reaction on a pain or migraine: what’s normal to feel after a session, and when to contact me.
By Dr Alexandre Fleury · Physician acupuncturist · ~3 min read · Updated October 2026
An acupuncture session is a moment that touches the body deeply. It is normal to feel effects in the hours or days that follow. Here are the most frequent reactions, so you can recognise them.
Most of the time, you feel a sense of relaxation and wellbeing, an impression of lightness and calm. Many people sleep particularly well the night after the session.
You may also sometimes feel very tired, with a need to lie down. This is a frequent reaction: listen to your body, rest, and if possible plan a quiet moment after the session. If you feel very tired or light-headed, wait before driving.
In some people, the session can temporarily worsen the pain or trigger a migraine attack for 48 to 72 hours. This reaction is well known and is not a cause for concern; it does not mean anything went wrong. Continue your usual treatments and let me know at the next session, so the treatment can be adjusted.
All these reactions are normal and not serious.
When should you contact me?
Contact the practice if you notice:
Very rare, but important to know: in case of sudden breathlessness or chest pain after a session, call the emergency services (15 in France).
