When I sit down on a chair without my legs crossed, the pressure on my perineum and anus causes some sweating and pain; I especially feel a chaffing sensation between my buttocks around the anus - specifically at the location where my pubes around my anus are located and rub together. For my perineum I again feel a prickly sweating tight heat as I m sitting down. As soon as I stand up the pain goes away, and on sitting down again it takes some time for the pain to return, in the same locations as before. To ease the pain around, and on, my anus I have been using a cotton pad to collect any moisture - this really helps! I ve found moisture makes my anus sticky and a bit sore. I ve previously been treated for Chlamydia and Gonorrhea within my anus but both were treated and symptoms disappeared. Ever since however I ve had this sensitivity/pain whilst sitting as I ve described above. Talc does really help in the mornings for my perineum and reduce any sweating chaffing around my anus and between my butt cheeks. Can you help?! What s wrong with me? Thanks in advance.
