Dr. Hanif warmly welcomes you! Thanks for consulting at my virtual clinic. I have carefully worked through your case, and can well realize your health worries. Being your physician, I want to assure, I will take care all of your medical concerns. This definitely is a matter of concern. You need to ask your physician for a prescription of antibiotic Rifaximin. Complete the course of antibiotics. Plus take omeprazole before breakfast. Take pedialyte so as to replenish the fluids and electrolytes. I preferably refer you to a gastroenterologist for proper evaluation of the reason for burning sensations. He may go for a proctoscopy or colonoscopy. It may be due to hemorrhoids too. Also ask him for complete blood count to see the hemoglobin levels. In bleeding it sometimes goes down leading to anemia. Hope I answered all of your questions. In future, if you need further, detailed and quick assistance on any health issue, feel free to ask me a question by writing my name as a reference in the start of your question. I will get back to you right away. Have a wonderful time ahead. Regards! DR. MUHAMMAD HANIF USA
