Thanks for query,
From your long history I can understand your sufferings and even by doing every thing you are not diagnosed and remains there and there.
What is my impression is you have got infected piles and due to remaing untreated there may be fistula in ano giving rise to recurrent infection giving all these troubles.
You go to surgeon and go for through examination of anal canal
and surrounding parts.
You require some counseling for your anxiety neurosis
so that you get some mental peace.
Ok and take care.
