about 6 months ago I felt cold so I rubbed my arms and felt swelling on my left tricep muscle. I felt the other tricep muscle and the one on the left is bigger than the right one almost like it was a little swollen. I felt around the area and thought I could also feel a lump amongst the swelling. I went to the doctor the first doctor said she wasnt sure what it was and to go back in 2 weeks time but I couldnt wait I was so anxious so the next day I booked another appointment and saw another doctor. he had a good feel of the arm and said it felt like a cyst he seemed quite confident. 6 months on and I've started worrying about it again I think this whole Coronavirus has made me have bad health anxiety and I've become fixated on this lump in my arm. I dont think it's a cyst because the actual tricep area seems bigger than the other side and I've started to get shooting pains aswell. now I'm not sure if this is because I'm focusing on it or if it's actually happening..I've had alot in the past where I've become obsessed with something health wise and I've created phantom symptoms..I'm convinced its a tumour and I'm really worried about it. abit of background I am a gym addict have been for 25 years I lift weights alot and pushups etc..I also had my own running machine that I lifted up and put down every day this was so heavy and would really hurt my arms..could it be that I had done trauma to that area or could it be a tumour..I need to go back to doc but I'm worried about going due to coronavirus etc
