Hi my name is Mark I am a 34 year old male I have a swelling just above my collar bone on the right side, it is soft and squidgy, it comes up for a couple of weeks and then goes down, I also have a pain in my shoulder that I can only describe as feeling like it is going to come out of its socket it is very painful, my arm has also gone a grey/blue colour for a few minutes a couple of times, I have been to the hospital and they could not find anything, I have been suffering with this for 2 years and it s getting worse. Any advice would be great thanks
