I'm a 32 years old non-smoking male. On 23rd of January, I started to experience stomach upset and heaty body (37.5 deg C). Thinking that i might have too much of deep fried food, I ignored it and started to drink lots of water. The condition didn't get better on the next day which I started to feel burning sensation in my throat, mouth, esophagus as well as my eyes. My body temperature remained 37.5 deg C. I didn't go to see the doctor but instead drinking lots of water and rest. The burning sensation remained for the next few days. Knowing that the condition might get worse, I went to see the doctor on 27th of January (5 days later). The general physician told me that I have infection of the throat and tonsil. She prescribed me antibiotic (cephalexin), lozenges, cough syrup, and panadol. It didn't get better. Finally i couldn't stand the burning sensation (heartburn) so i decided to take antacid (zellox-II) and immediately i feel relieved. The heartburn sensation disappearred overnight. The next day, I visited another doctor and explained to him my condition hoping that he would understand and write me a referral letter to the Gastroenterologist. He refused. He prescribed me more drugs: Zantac Ranitidine (150mg), antacid zellox-II, Zecuf, antibiotic (cephalexin), paracetamol, and cough syrup. This is when problem occurred. I started to experience soft light yellow stool (very little as i didn't eat much), diarrhea (>3 times, little too) , indigestion, nausea, and bloat. I started to get worried and didn't take the medicine for the time being. Please advise me what to do now. Thanks in advance.
