Hello,
Constipation is followed by development of a condition called a
fissure in ano in which there is formation of a cut at the anal verge and since the area is very sensitive it causes a lot of pain on passing stool.
Passing stool dilates the anal verge as a normal process thus causing recurrence of pain and ulcer formation.
Infection therein causes peri-anal itching and also changes in skin due to
dermatitis, local sweat collection, inability to clean the area properly due to pain.
I would advise you the following in such a situation:
- Sitz bath in a tub with warm water
- Take laxatives and stool softeners
Send the stool and blood for investigations and if there is any evidence of infection get a prescription from your Doctor. If the problem persists, then you may need a surgery.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant
