Hi guys, Good a bit of issue, about 2 weeks ago, I noticed a pea size lump on my anus rim. Prior to that about a week before I was traveling oversea in South E. Asia and got diarrhea for about 2 days and had very red stools. I went to the clinic and they suspected food poisoning gave so medication to solidify my stool. To date, the pea sized lump is virtually gone, however I have noticed a white pimple spot near the anus. A bit worried about it, I ll definitely be seeing the doc next week when I have time off. Seeking a bit of insight to put my mind at easy. Look forward to your assistance.

Hi, Dear,Thanks for the query to Chat Doctor. I studied your problem in depth and I understood your concerns. Cause for pea size lump around anus-In my opinion your small perianal lump is -Sentinel pile, which would need confirmation from ER Surgeon, as it appears to be there long back, simultaneously and got detected now. This is non-malignant condition but needs treatment by an ER Surgeon.Hence, stop worrying about it, as it is not a CANCER as you fear and think, but do check it up from ER Surgeon. For Final Diagnosis and treatment needs clinical data from a Doctor. And Hence for further treatment I would advise you to Consult ER Surgeon, who would treat it accordingly. This advice is based on the facts from the history you give and needs further clinical check.Hence, I would advise you to check with ER Surgeon. So don't build up wrong concepts and create more psychic complications in you which would increase risks and costs to you. Hope this would relieve your problem.
