Hello, I have gone through your query and understand your concern. You have to understand that back pain with bloating can occur together in a number of conditions. Sometimes foods you eat that cause bloating can lead to gas pain that seems to radiate to your back. It may also be caused by Gall stones, kidney stones, ovarian cyst, urinary tract infection (UTI), tumors, such as an ovarian tumor. You need the physician help for simple physical examination. He may ask detailed history of the pain and bloating and associated symptoms like blood in your stool, vomiting, blood in your urine, headache, heartburn etc. Based on the findings and clinical diagnosis, he may recommend any further investigations or he may treat with some antibiotics if he suspects any infectious origin. Hope this helps. Please write back for further queries. Wishing you good health.
