question: Hello doctor,My father's age is 56. He is diabetic for the last two years and the only medicine he takes is Metformin 500 tablets daily before meals twice a day. He is been complaining about a continuous mild pain in his pelvic area since last month and he says it hurts more usually after he pees. When he rubs that area he says the pain goes away. Currently, he is taking Glyciphage 500 tablets.
