I am 30 years old. Recently I was diagonized with Erosive Gaestro Dudonitis. I was given HP Kit for 14 days. Then doctor prescribed me Mebex. After two dose of mebex the anal itching started. Before taking mebex I did not have anal itching. I again contacted doctor. He told me to take the second dose the next week. I took the second dose and the itching went away slowly. For 3 days I was alright. I again had the itching on the fourth day. BUt it was mild. How can I confirm if I had/have worms in my intestine.
