It is painful in both abduction and flexion at 90 degrees when externally rotated and seems to be in a painful arc between 90-140 degrees.

Isometric contraction seems to limit the pain, however concentrically contracting from full ext rot to int rot increases the pain.

Around those landmarks i cant feel any painful areas.

Forgot to mention went to see the Doc, he said i had ruptured one of my biceps heads. However wouldn't this show a lack or strength/ increase of pain during flexion?
