Hi, I have been experiencing a slight pain in the mid-left side back region. when i touch the muscle in that part, it slightly pains and also causes a roaring noise in stomach for some time. I have already done CT scan of abdomen and pelvis and it was negative. I get sound sleep of 8+ hrs at night, tried using muscle ache pain killers but still slight pain there. it is lesser than before, I feel it while having food as well. putting cold ice bag to this area. how do i cure this completely?
