Hi, I Have Had Itching Around My Anus And Taken

Hi,

I have had itching around my anus and taken tablets for pinworm, this has stopped it for a couple of months however I still have it.

The itching has now stopped however it is now a throbbing sensation which is sometimes hot, I go the toilet more now and often have stomach cramps and loose stooles.

I have had this since July 2015 and been the doctor 4 times about it.

Please help
