I started to have pain and bloating in my abdomen, mainly on left side 4 months ago, in the last few weeks my left side and back, down to my thigh has been puffy and painful with my lower back in agony, I've now got a small puffy and painful lump coming on my tummy and myright arm is weak and aching painfully. Im so tired and can't concentrate to the point where I don't feel I am safe to drive or work but I'm getting through. I've got scans comming but blood tests have come back clear. What could it be? I'm really frightend now and I feel the GP isn't moving quick enough to find out
