I have constipation, one day i found out that my anal area is burning. The interesting thing is that when i go to bed within one hour the pain vanishes, even in the morning there is no pain, but when I sit on chair or or car or others then the pain starts. After a few days I met with a doctor, he told me that I had a little anal fissure. He prescribed me antibiotic, sitz bath and nitroglycerin ointment. Now there is no fissure but pain is still suffering me. When i don't sit, there is no pain, but it starts while i sit. I also have some homeopath medicines suggested by the homeopath doctors, but i don't know the names of those medicines. I do not feel any problem during bowel movement and there is no bleeding. Only around the anal get swelling like the ant's bite. Any one can please help me?
