Hello. I would like to help you find an answer.
What you have is most likely hemorrhoids that are being pushed out after a BM.
These can cause intense burning and itching. The enema is basically cleaning you out and relaxing the anus so the hemorrhoids don't push out.
One key is to take a stool softener orally to loosen the stools. This will help.
Also, you should go to the drugstore or see your doctor and get some cream to sooth the inflammation.
Finally if none of this works, you probably need to see a doctor to have them removed.
If you have had hemorrhoids then that makes hemorrhoids even more likely.
I am sorry you don't like my reply but I am quite certain this is the problem.
You need to do what I suggested and also see a doctor for an exam.
He will confirm the hemorrhoids.
