Right lower back pain. Properly.

I'm having a mild heaviness with pain on the right side of the spinal cord on the back. Sometimes this pain is moving near the lower right waist to the navel. Often this is accompained by a severe heart burn, excessive gas (burping+wind pass), burning stool and constipation too. I feel like sometimes even my urine is also burning. This burn feeling reaches to my hands & finger tips also which eventually ends up giving me small prickly heat type allergy. Im able to pass urine properly but not able to pass stool that smoothely. Im also having excessive hairloss. The gastroentrologist suggested me Rcifax 550mg & Cintodoc medicines. But i dont find any improvement rather my pain is getting worse everyday. My ultra sound report states everything normal. Please help me. Im worried a lot since no one is able to diagonose my condition properly.
