Been have digestion problems, back pain and fatigue. Dr examined my stomach and has suggested blood tests for anemia and celiac. I have very badly seperated stomach muscles and small hernia near tummy button all seen on scan of abdominal wall scan this year. Felt stomach last night standing and I can feel a small pea sized lump near left hip. It's squishy and moves. When I lie down I can't feel it. What the hell is it? I am very skinny ( 6 stone 9) so my mum just thinks its because if that I can feel everything. Could it be just muscle?
