For back pain I was prescribed Painkillers 10 days back. After that I a, m getting semisolid stools, nearly 3 times a day. The stolls are not loose, only semi solid. Now I am having severe itchiness in the area around the anus. I am fat and my hands I cannot reach there to scratch too. What could be the line of treatment in this issue. I want immediate relief as the itchiness keeps me very disturbed constantly.
