I came off my bike a few weeks ago and landed on my left shoulder, i hit some old tram lines and it flung me off my bike. My left arm seemed to be a little better but at football yesterday i landed on it again and now it hurts again, not all the time just when i seem to be pulling doors open or lifting etc. any ideas? i will be going to GP when i can get an appointment, but wondered if anyone else has had anything similar.
