The most common side effect of acupuncture is a feeling of deep relaxation and euphoria. Most patient fall asleep or go to a semi-conscious state during treatment and awaken feeling calm and deeply refreshed. Many patients report improvements in sleep, digestion, elimination, mood, energy, and periods. Possible adverse effects include bruising from the needles, fainting (if you are prone to fainting easily), and feeling tired (if you’ve been running on fumes). Occasionally, in the course of treatment a small percentage of people will experience a slight flare-up of symptoms as the body is releasing old patterns. However, should this occur it’s a natural part of the healing process that resolves as treatment progresses. If this reaction occurs, it is mild and does not last any longer than 24-48 hours, and once it passes, the patient feels better than they did prior to treatment. Most patients leave every treatment feeling much better than when they first came in.
