I have been having many shots for my back, hip and shoulder. A couple of months ago I had another shot last month I notice an indention in my lower back. the size of a quarter and know it is the size of a baseball and it hurts so much and starting to go to my butt check. Is there any way of getting rid of pain if i cough it hurts and know my tail bone has no cushion I sit on it and you can see the bones profile. Thank you Deborah
