I could still feel the needle hours after my treatment. Is that normal?v

On occasion, this does happen. When a needle is inserted into an acupuncture point, the body’s response doesn’t always stop when the needle is removed. This can include a lingering sensation in the treatment areas. Around five percent of patients will report back after treatment, saying that one or more areas had continued to ache or “hum” for an hour or so after their treatment ended.
This is nothing to be worried about, but you may feel free to mention how you felt to your acupuncturist the next time you are in for a visit.
