If you had General Anesthesia which I assume would be given for any orthopedic surgery above the waist, you should have been given either Morphine or the non narcotic Toridol or Ultram by injection to control post-surgical pain. Ibuprofen should only be taken on a full stomach and is never given orally until the patient can eat normal meals (approximately 48 hours after surgery). I suggest that you immediately see a Gastroenterologist who will probably do an upper G.I. exam with a scope to determine if any damage was done to your esopagus. Based upon what he sees he would in all probability prescribe a combination of a Proton Pump inhibitor (Prevacid or Nexium 30mg.) and an acid blocker (Pepcid 20mg) for a period of 60 to 90 days until the affected area heals. At the same time you will have to adhere to a strict diet of low fat, no spices, or fried food.
This condition is called GERD. I suffer from it and must take these medications for the rest of my life.
