<s>[INST] I more often than not for the past 2 months, have had a slight pain on the right side of my abdomen…sometimes higher or lower or sometimes left side (way more often right side). Also, sometimes when I eat I feel I need to go to the bathroom, and only ended up passing gas (makes me feel better) For the first time, I saw what I think it was a little bit of bright red blood at the end of my stool. I have no pain after eating or before going to the bathroom or after. But, I’m a little concern on what is going on. I checked with my pcp, and she gave some pills for heartburn (runs in the family, bad acid reflux) She asked me a LOT of questions and even checked my belly pressuring everywhere and said everything was fine. But, I don’t feel satisfied. I’m 31 years old, 6-3 280 lbs and honestly don’t have the best eating habits. I work on the road so; I eat in a lot of chain restaurants. I had blood work done two monhs ago to check my liver, and everything came back looking great according to the doctor. Any suggestions or ideas? Thanks [/INST] Hi,From history it seems that you might be having acid reflux with likely of having chronic GI infection.You might require one course of ofloxacilin, tinidazole medicine course for 3-5 days.Take Omeprazole type of medicine.Change your food habit.Avoid fried and junk food.For having passing bright red blood at the end of passing stool without pain indicates you might be having internal hemorrhoids.Consult surgeon and get examined.Avoid constipation and take plenty of water.Ok and take care. </s>
