To Softvision about the pain in the L shape. Exact same issue with mine, i just got my Wikipedia reference-linkmri done yesterday and i'm waiting on the results. What the doctor took a guess at was that it's a Bankart Lesion or a tear in the labrum which is the muscle that connects to the bone. From what i hear the only way to go about permanently fixing this is surgery. I've opened my eyes too it as well. Now i just need to win the lotto.
