Hi dear
Welcome to HEALTH CARE MAGIC
As you have described the symptoms all fit in to the diagnisis of
anal fissure.
Cause is usually
Constipation (hard Stool).
Diet changes are quite helpful like
Take food full of fibres,
No juices ,
Take lot of friuts (complete fruits alongwith its covering if eatable).
Avoida maida
Use bread with all its husk.
Lot of salads
Lot iof Vegetables
Routinely going to the toilet at fixed timing. never delay.
Apply some anaeasthetic jelly or cream in and around anus, before and after passing stool. It will alleviate your unbearable pain and also relax the anal sphinctor to allow the stool passage easily.
Use some laxative like isabgol husk or some laxative medicine ( it will act as
stool softener)
sitz bath will help you alot.
Also you should be investigated for the
thyroid profile.
Hope your query is answered with your satisfaction.
Thanks
