Hi,I am going to see a doctor tomorrow morning, however, I want to do some research right now.  I have a lump on my anus.  It is right on the exterior/exit, and protrudes from my anus.  It isnt a hemarrhoid, that I am pretty sure.  It is actually under the skin.  The skin shifts fine above it.  It isnt soft, more firm, and is sore to the touch.  There isnt any blood, as it is quite completely under the skin (as stated before), and not connected to the exterior skin it seems.  It protrudes out from my anus.  It just came on sometime today.  I dont think I had it yesterday.  I havent had any difficult bowel movements or anything. I have, however, been moving boxes to my new house.  Also, I dont know if it is important, but I broke my leg June 2, had major surgery, and am still recovering, albeit, not on any medications.Any ideas what it may be?

Welcome to Chat Doctor. 1. The history suggest it's an infective etiology, hair follicular infection which is in the early stage in subcutaneous plane.2. As its sore and painful suggest active infection. Treatment mostly include a course of antibiotics with symptomatic treatment will help.3. As a remedy - do not squeeze, press or scratch the area - as that way you will be complicating the lesion and increasing healing time. 4. The symptoms you have mentioned does not seem like any operative procedure is required, so not to worry about it.5. An ultrasound might be needed to know the extension of the collection or lesion. Good luck. Hope I have answered your query.Anything to ask do not hesitatehttp://doctor. ChatDoctor .com/doctors/ Chat Doctor.
