Since May I have had stomach cramps and bloating and abdominal discomfort. I took all antibiotics and anti ulcer drugs. Had some basic tests and all came clean. Last week I weighed myself to find out I lost 5 kg. I went for a scan and all internal organs are doing well yet my stomach hurts really bad with random bowel movements and diarrhea at times. A doctor said I go for a HIV test and right now I'm dead scared.
What could possibly be the problem here. No fever, no headache, no vomiting but sometimes I am fatigued from deep thoughts.
