ostarine is a healing sarm.. ostarine is NOT the culprit here and its clearly an injury of some kind... you also tried deca, which has no healing capabilities but absolutely lubricates joints and masks injuries and pain and that is not working either, which indicates you have something else going on there, but noone has any clue what that could be with any sort of certainty.. it would all be an educated guess, which ultimately tells you nothing aside from a possibility but it sounds like you should go get it checked out...
