I have worm like movement on the left side of my back..there was a lump but it keep coming and going,it stop when I put antiseptic ointment on it (salvon) but start back after a few minutes,it s on going,so bad I can t sleep at night...plus my stomach is unusually bloated,I am fairly, skinny but tummy protruding out,even when I haven t eaten anything...I had and stomach hernia last year,which contributed to acid reflux.,but don t think it s related.
