My Brother complains about chest pressure pain, a growing fire in his lower back to his mid-back, but he thinks it is his stomach, because he feels stomach pain. He says he feels like acid. That his stools feel acidic. He went to see a stomach specialist, but they only prescribed him strong anti-acid pills. However he has been taking the pills, he still feels sick, and that the pills have no affect on his condition. And now he is complaining about feeling very hungry, even though he just ate! He farts and burps even though we hardly eat anything at times. He works all day as a server. He is in good shape. Age 28. 165lbs. The problem has been coming and going for months, but now its really bothering him. He says he feels his back starting to burn crawl, low to mid, usually around 2pm in the day and persists til sleep. This is all I can relay for now. Any help?
