About 10 years ago I woke up in the morning laying on my stomach with my head on a bunch of pillows and I was in so much shoulder and neck pain I couldnt move for four weeks.  Went for MRI and found out that I had herniated 2 of the discs in my neck. The pain slowly went away but I had numbness in my thumb for quite a while and every once in a while, If I hang on the computer too much or do alot of cutting my upper arm will have spasms and pain will throb. If I hold my arm up in the air it will go away eventually.. I havent had that pain in a while.. but now my arm is swollen. My  neck feels stiff and achy. My entire arm is swollen.. I noticed my fore arm was swollen a few weeks ago and I went in for a flu shot and the nurse commented on how much bigger  my right arm is than my left. The upper part of my arm is even more swollen.. 

does anyone have a clue what it might be. I am going to make an appt with the dr.. but I am really really worried this could be something devastating...

Thanks :)
