Balmex and fiber
Get back on a regular diet
with plenty of fiber
and water. Gently cleanse the perianal area with a mild soap and pat dry.
Use balmex (yes, what's sold for babies bottoms) on the perianal skin to help the skin heal. You are aiming for a stool that is formed but deformable- not hard, not smeary. Use premoistened wipes (not baby-wipes) to cleanse until healed. If not better, see your doctor!
