prolonged problem

Dear Doctor

I am facing a problem since almost 5 years from now. I want to seek you advice if you can help me out please.

The problem is as following

-The problem started with prolonged constipation due to my eating habit (taking less-fiber diet)
-It started bleeding with bowel movements and a little growth appeared on anus like the size of a mung bean
-Doctor suggested 'R13 (contains graphite)' for immediate remedy
-The bleeding stopped, and the doctor switched to 'Aesculus 30 and Bio-Plasgen 17'
-I used it for 3/4 months and then stopped taking medicine

Now

-I still have some little growth on Anus
-It is just like the size of a mung bean (moong daal)
-Whenever stool gets a little hard, it is scratched, it starts itching afterwards (sometimes i feel scratching inside the rectum as well)
-Then in next bowel movement, a few big drops of thick blood comes
-if the stool hardness still keeps, it then starts bleeding with stool, fresh red thin blood
-during and after bowel movement, the inflammation and pain stays, (sometimes for an hour or more)
-i keep taking on high-fiber, less spicy food with loads of water, after 2/3 days bleeding stops, and after a week or so the burning/itching/pain goes away

this problem is now occurring more frequently, one thing to note is that the growth on anus becomes a little bigger when it is paining/bleeding, when the problem goes away, the growth becomes smaller, but it still keeps there. it is never disappeared after i first get this disease
an sometimes i feel scratching inside at the end of the rectum as well
