Hello
I share your concern
Bumps around the anus might be related to hemorrhoids, infected anal gland or ano genital warts.
Here I would like further details to help you better like
your age and relevant medical history
Since how long you are having this problem?
I would advise you to follow these guidelines
1. Avoid
constipation by taking laxatives or stool softeners
2. Have lots of fresh fruits and vegetables or
dietary fiber supplements
3. You should apply antiseptic ointment like mupirocin or soframycin and maintain good hygiene.
4. Sitz bath twice daily,( by sitting on buttocks in a bath tub filled with hot water for 10 minutes)
5. You should take anti acidity.medicines like
pantoprazole or
ranitidine group of drugs with antacids for gas and nausea problem
Hope this helps you
If it doesn't improve in a 4.to 5 days than you should see a
general surgeon or gastroenterologist for further examination and definitive treatment.
Best wishes
