Sir I am 24 year male. Suffering light lower and middle back pain over 3 months. And sometimes both side abdomen light pain when gas occurred. Usg and lft normal. Occult blood test trace. But I ear carrot, cauliflower and beans before the test day. Gp says don't worry. I am eating duphalac oral solution about 10 days. And after take this stool clear and pain almost 99 % reduce. I am sitting daily 11-12 hours. What I do sir. Please says some medicine and advise.
