hi,
About few weeks back I had an antibiotic treatment (for tooth infection) that caused me few days of constant diarrhea (I actually had to terminate the treatment).
Following the diarrhea, a small lump has formed on the edge of my anus, that itches and is sensitive to touch/pressing and a bit sensitive during bowel movement.
No significant pain, no bleeding...and another thing - it appears to worsen when I wash the area with soap/water in general. I thought it would pass, but it's been about 2-3 weeks now...
Can you please help. I'm 32, male.
