In September I noticed a swelling above my bellybutton, I went to the gp and was told it was nothing, asked me if I had health anxiety about cancer etc. 
This swelling did not go away and I'm convinced I can feel a lump under the skin. Went and saw the director at the gp surgery before Christmas and was also told it was nothing. I am anxious beyond belief. I have no symptoms, haven't lost weight. Can eat fine and go to the toilet fine. I keep thinking I have loads of lumps inside of me and when I am slouching and I breathe my stomach makes awful noises feels like loads ofnpopoing sensations in my left side, I can sometimes feel these if I sit up to quickly. This swelling hasn't gotten bigger and if the lump has I really haven't noticed it. The swelling has a line coming out of it that travels up my midline into a small bump. Been told it's not a hernia or a muscle separation. I know it's probably google and my mind playing tricks on me but I'm convinced that this can only be cancer. I'm 16 years old and terrified. I have decided to go for a private CT scan early January to try and figure out what this is.  Has anyone ever had anything similar?
