the other day for the first time my scapula locked right up good thing it happened while i was at physio(they were able to unstick it ) , what troubles me is that each and every time i lower my arm to my side it will go purple or blue sometimes grey if i leave it there for any time i know this is a venous issue but could it be something else also it feels as if it going asleep but not , i really want to get back to all the things i love to do my goals now seam so far out of reach i know i have the abilities but concerned if i try anything i might cause further damage and what if i go to the doctor and he can cannot find out what going on i hate just being pushed on from one doctor to another very down in the dumps
