Hemorrhoids :: Anusol, Scheriproct, Prep H, Anugesic, Xyloproct - Nothing Works

Hey guys so I'm a healthy 26 year old who has never really had any health problems. unfortunately that changes last July when I discovered an external hemmy (I think) hanging out of my backside. It hurt like crazy and swelled up every time I had a poo to the point I couldn't do anything besides lie in the foetal position till the pain subsided and the swelling went away. I tried everything from anusol, scheriproct, prep h, anugesic, xyloproct. The symptoms seem to get better for a while then worse. The last straw was pus and blood coming out of my backside and a little pimple like thing on the back of my hemmy which got me really worried. I went to the gp for the 5th time on the 4th of Jan and he finally referred me to a specialist as well as prescribing me some antibiotics as he said I had an infection. I was on metronidazole for 7 days which was horrible as it gave me horrible side effects such as nausea, vomiting, feeling very weak and dizzy etc. I had the oral course for 7 days as well as a suppository and was finally feeling better down there. No pus is coming from my backside but my small boil on my hemmy still has pus and every so often drains itself. I have got an appointment for the 8th of March which is reassuring but today I had a bm which was followed by bleeding which hasn't been the norm for about a week now.there's a bit of pain after but nothing in comparison to the pain I used to have before. I'd say I'm at a 3/10 right now. I'm worried about a set back and also about possibly having surgery because the stories I've seen have not been reassuring at all. I'm scared I must say (luckily I'm not constipated because I don't need that right now). Anyone know what I should do it what to expect or what is likely to happen?
