I am sorry to hear you are still experiencing elbow pain despite taking Tendocare for a month. It can be frustrating when healing takes time. Since this supplement, which supports tendon health, has only shown minor improvement, your elbow may need a more comprehensive approach. Pain when lifting light objects like a mug often suggests tendon irritation, such as tennis elbow. I highly recommend consulting your doctor or a physical therapist. They can properly evaluate your joint and suggest targeted treatments, such as specific strengthening exercises, a temporary support brace, or physical therapy. For now, try to rest your arm and avoid movements that trigger the pain.
