Hi

I Started with a small lump deep in inner thigh checked with doctors a few times said probably a swollen lymph gland but over the years it's grown to the surface near groin area also there is now two an inch apart solid hard cylindrical somewhat but now have appearing on my arms but flat started squishy but quite firm also can feel solid mass in arm like the ones in my leg but the ones just under skin are flat and spread out..I also have a swollen knee that blew up on other leg and a flat lump on top of foot .... plus a rather swollen abdomen ..but have gained so much weight that it surly can't be cancer I have terrible lower back pain on one side and totally breathless doctor finally did a bowel cancer test that came back fine then sent me for a ultrasound  scan on abdomen and thigh 2 weeks later still no results and more lumps appearing in upper body any ideas ? It's driving me mad !!
