Dear- thanks for using our service and I understand your complaints. You can have increased in the gas pattern which can radiate to the back and give you back pain. The reason for increased gas could be secondary to the food that you eats, as vegetables,like broccoli and califlower . However, you can have some chronic irritation of the stomach as gastritis that can give you the same complaints. Pancreas inflammation can produce these symptoms too. Try to avoid a lot of vegetables and spicy food, also coffee and milk products and see if helps. If it doesn t ,you might need to see a primary care doctor for an evaluation. I hope my advise has been helpful Dr.Sara
