I have a sore elbow and it causes pain when i lift things.?

May be tendonitis: A person who gets a numbness, soreness, or tenderness (to pressing on it) where the muscles attach near the elbow may have tendonitis . . . But he will usually know what caused it. The cause is overuse of the arm during the past day or two. Icing the sore spot and taking some Motrin can help. He can wrap the sore area with an over-the-counter elastic band, which will spread the muscle's force out.
