Question: I have two small lumps near my anus, which sometimes discharge blood and yellowish fluid, and then disappear for a while. They feel uncomfortable and I would like them to go away. Please advise.
You could be suffering from one of a number of conditions including piles, fistulae or cysts. There are also a number of rarer possibilities. It will be necessary for a doctor to closely examine one of the less attractive parts of your anatomy in order to make the appropriate diagnosis.
Almost certainly you will need some form of surgery to remove the cause of your discomfort.
If piles are present, injecting into the piles, or placing a small rubber band around the base of them may cure the problem, but in some cases, surgical excision is the only option.
A fistula is a microscopic tube that connects the inside of the gut just inside of the gut just inside the anus, to the skin beside the anus. These tubes become infected and painful periodically, and then discharge pus and blood. The only treatment is surgical.
A cyst can occur on any part of the skin, and may occur on your back as readily as your anus. There are many different types of cysts, including those that can be caused by blocked sweat or oil glands, ingrown hair, or infected hair follicles. Although these can burst and drain, they usually return unless they are cut out completely.
Don’t continue to suffer discomfort for months, suffer embarrassment for a few minutes instead, and see a doctor soon.

Question: I am bleeding from the back passage after passing a motion. Is th serious?
Bleeding of this nature is most commonly caused by piles. These are dilated veins that are caused by constipation and straining. When hard motions are passed, the small veins around the anus become damaged and become thin walled and swollen. Further motions can easily rupture the veins, and this leads to bleeding after going to the toilet. Sometimes the blood in the pile becomes clotted, and they may become very tender.
There are other causes for anal bleeding that include diseases as diverse as cancer and a simple tear, so it is always wise to have this problem checked and properly diagnosed by a doctor.
