Burning around the anus or intense itching in your anal region can be a very embarrassing and irritating condition. The burning sensation in the anus can sometimes occur after a bowel movement, eating spicy foods, or because of hemorrhoids. However, a number of skin conditions like eczema and psoriasis can also cause a severe urge to scratch your anus that can lead to anal burning. Also, the fact that the rectum is prone to bacterial infections can aggravate the feeling of burning even more.
Depending on the cause of the burning feeling around your anus, the intense itch may come and go or you may have persistent itching. If your anus burns after a bowel movement and you notice a small amount of bleeding, this could be caused by an anal fissure. If the burning sensation in your anal area doesnt go away and you have other symptoms like constipation, diarrhea, or anal leakage, you should visit your doctor. You should also visit your doctor if you have any kind of bleeding from your bottom.
