Regular stomach troubles. Fruits.

Hello, I have been suffering from digestive issues for a lot of years. There is a general discomfort in the right side of my abdomen. This involves radiating pain that in bad cases shoots up till my thigh and also testicle. However, I notice that followed by this discomfort, I more often than not, need to pass gas. The entire pain disappears or reduces drastically. Recently I had a terrible stomach ulcer (I presume). I ingested a raw green chili which immediately felt like my food pipe and inner stomach had burnt. Ever since then, the above mentioned issue has aggravated many fold. I cannot sit because the pain shoots though my leg and testicle.. passing gas relieves the pain.. standing and walking reduces it. There is a pain radiating from my right lower back to front abdomen sometimes. Could you kindly guide me here. diet involves chapattis, parboiled rice 80% of the time, else white rice, lentils. stir fried vegetables. Chicken, fish. drink water moderately. irregular fruits.
