Hello and welcome to Healthcare Magic. Thanks for your query.
Pain which associated with ba lump in the anal region can be due to the following common causes
- hemorrhoids (piles)
- anal fissure
- other swellings like an infected sebaceous cyst
You will need a proper physical examination, including a per rectal examination
to ascertain the cause of the your pain and swelling.
is one of the important factors which can worsen the pain in most of these conditions, especially when there is an anal fissure. So, I would advise you to take a fibre-rich diet (more of vegetables and fruits) and drink plenty of water.
Wish you all the best.
