Acupuncture is generally associated with mild discomfort rather than significant pain, though the experience varies from person to person. During treatment, you may feel: A brief pinprick as the needle enters the skin. A dull ache, tingling, warmth, heaviness, or a mild pressure around the needle. These sensations are common. Little to no sensation at many needle sites. After treatment, it’s common to have: Mild soreness or tenderness for a few hours to a day. Occasionally, a small bruise at a needle site. For treatment of Lateral epicondylitis, needles are typically placed around the elbow and sometimes in the forearm or at other points on the body. Most people tolerate the procedure well. If you experience sharp, severe, or persistent pain during acupuncture, you should tell the practitioner immediately. The needle can usually be adjusted or removed. If you’re asking because you’re about to have acupuncture for tennis elbow, it’s reasonable to expect mild, brief discomfort rather than intense pain.
