Hi, thanks for sharing your health concerns with HCM!
If I were your treating Doctor for this case of a lump around anus, I would come up with three possibilities, these include:
1. skin or hair
follicle infection due to some friction injury , worms, fungus, piles, fistula or fissure!
2. The second possibility is of an
ischiorectal abscess 3. The last possibility is of some
infected cyst or
benign tumor / tumor like condition like
rectal polyp or skin tag/papilloma!
Overall, it is possibly inflammatory and not to worry much about this!
I suggest you to go for stool examination and see a surgeon for a physical examination and some medicines;
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
Wishing you good health.
