My son experienced several canker sores a year ago. His mouth and his throat were loaded. They grew about an inch and was then down his esophagus. He ended up in the hospital and they did all kinds of test for HIV/Herpes/bloodwork/Biopsys etc. All negative. He was on Morphine, viral antibiotics, and was almost to the point of being tube fed and they started to shrink up. After he was released with no dx. they came back every 21 days. The Drs. were more concerned with taking pictures of the ulcers for teaching then they were helping him. He ended up with a $17,000. Hospital bill and no cure. He got them every 21 days (like a period) for the next 9 months. He was put on prednisone, valtrex, and they took him off the prednisone and the valtrex dried his sinus out and caused nosebleeds. Then Bang...they stopped in July and he hasn't had them back until this week. He is in the Albany area and looking for a Dr. to help him. There first dx. is possible Aides. He has been tested twice during the last 2 years. He is newly married almost a year and doesn't know where to go from here. What to take to relieve them when they start, what dr. to see. Has anyone experienced a situation such as this. Any info would be appreciated.
