I had burning pain in my stomach 4 weeks ago and started prilosec for 2 weeks. I didnt have any burning pain when taking prilosec but the next day after finishing it, i started get burning pain again. I dont drink, smoke and was tested negative for h. Pylori. I was taking advil for headaches and prednisone for sinus inflammation but stopped it a month ago. Wouldnt prilosec healed the ulcer by now?
