The occurrence of tendinitis is mostly due to local overuse and trauma, which causes local stagnation of qi and blood, and blockage of the meridians. As a result, there may be adhesion and pain in the tendons. Acupuncture is particularly effective in dredging meridians, activating blood circulation, and relieving pain quickly. Therefore, acupuncture can be very effective for tendinitis. We can perform acupuncture treatment by needling the painful area and selecting points along the meridian. Generally, the effects of acupuncture are favorable. If combined with other conservative treatment methods, it can produce significant results.
