I'm a 25 year old female. I'm fit and have no major health problems. (I train in acrobatics twice a week, so do spend some time upsidedown on my hands, but there was no recollected injury) However in the last few months i have started having problems with my right shoulder and arm. It started with a slight loss of control and then developed into not being able to internally rotate the arm (putting on a jacket would be very painful) It has developed, it no longer hurts as much, hardly at all, but if i cross my right arm over to my left side i have very little control of my right hand. Then today it just started random twitching.
Is it possible i have some nerve damage in the shoulder perhaps? I am a from oversees and only in America until July and dont have proper insurance, when i return to the UK i will be able to get medical tests, but if there is anyhting i can be trying in the mean time, it would be rally usefull
