Welcome to Healthcare Magic!
The anal sphincter goes in for spasm when there is fissure and this causes severe pain
during bowel movements and may also result in bleeding .
The treatment is to relieve this spasm and aid smooth bowel movement.
Though topical nifedipine
is effective, she is not getting adequate relief.
She can use 2% diltiazem
Sitz bath should also be done.
Though fiber supplements are usually prescribed to aid smooth bowel movement, it should be avoided in her case as she is having a flare up of ulcerative colitis
Does that answer your question?
