Nope, dont know what the cause is. I have been thinking about this the past couple of days. If I dont know whats causing the problem and address it, it will just keep coming back.
I bit the bullet and went to see her yesterday, she told me I need to test is and to go to the Dr when the pain reaches an 8 then it will be steriod injection into the bursa

Well I've decided if she wants me to test it, I bloody well will.
