Pain in upper inside of right arm, just above inside inner elbow has some pain and tenderness whenever i exert force to lift something. sometimes feels numb in upper arm area. stretches help sometimes been happening for 2 years?

The issue is whether there's inflammation,strain or overuse.of one of the stuctures in the area of the right elbow or inner upper arm or whether there's a nerve impingement affecting the right upper arm. A physician would examine the right elbow,& upper arm & put you through some maneuvers in order to make a diagnosis & advise you. I favor some.chronic inflammation of a biceps tendon.
