Hi, I have an extremely large (feels about the size of a tennis ball) extremely sore lump on my left bum cheeck near my anus. It hurts to walk, it hurts to sit down, it hurts when I move, it hurts when I move my legs. And I have been feeling very unwell, feeling sick with a very sore stomach, and also feeling very bloated as well as feeling dizzy with a constant sore head. I have PCOS, I don t know if it is something to do with this but I just thought I would tell you. Any help would be greatly appreciated. Thank you so much. Kind regards Stephanie
