Hey there, u should see a doctor right away, to calm them itchyness try sits baths, witch are cool bath water, where it sit in it and soak the area, make sure the water is not to hot, only put the water high enough to wash your bottom. Keep your stool very soft so you are not stressing the anus. This is how anal fissures can be caused by, as well as hemmoroids, by forcing the stool it strech's it and forms cracks, on the inside that are hard to heal. You need to see a doctor as you may have a sever yeast infection or a combination of both going on. Please don't be embarrassed, keep it clean and put some hemmoroid cream on it (your bottom)to keep the skin soft. good luck ww
