Thats fantastic your dr doesn't seem to think it is anything to worry about. It is awful when you start to get paranoid thoughts in your head and then it makes you stress even more and then your mind goes into overdrive. I had this lump on my arm a while a go and all I kept thinking it was cancer, but was too scared to go to the drs to have it checked. It pretty much has gone now so I figure it was just a cyst. If it had gotten bigger I would've gone to see him.
