Hi , I am 21 years old college student. I am from Pakistan. I was having loose stool and lower back pain from last two months almost. I was ignoring it and if any day problem get worse, I would take Pepto Bismol and problem would be solved for 1-2 days. Then I had Dengue fever, I went to Doctor and explained him everything. He thought may be I am having fever because of stool so he started giving me injections of OXIDIL [Ceftriaxone 250mg] twice a day, with paracetamol and Entox-p (attapulgite 250 gm) and ciprox (ciprofloxacin) and i started feeling better and when reports of dengue fever caMe he stopped all medicine except paracetamol. Then My stool problem was also solved but from last 3-4 days I am again having loose stool. My stool test is normal I dont have faecal blood in stool, no ova, parasites or cysts were seen in my stool. But I am still having loose stool but this time no pain in lower back but little pain and pressure in stomach. Some days I need to go to toilet for more then 6 times and some days only 2-3 times. Sometimes stool comes in very small quantity but sometimes in large quantity. My stool is yellow like a baby's stool. I ahve again started taking entox-p and ciprox but it doesn't seems to work. I am very worried, please help me. What is this? Is this just IBS or I am having other problem like cancer or HIV???
