Abscess on my face

Hi hope someone can help me a bit. I have been getting hard red lumps on the right side of my face. This first started a month ago, when I thought I'd had a bite from a bug, I put some bite relief cream on it, and after a few days it went, it was a bit itchy, I remember. After two weeks or so it came back up again, damn how could I have abite in the very same place I thought, and again put on the stuff and it went away, then maybe a week or two later another lump appeared a little away from the first one, same deal, a bite I reckoned, then last week a 4th turned up in the middle of my cheek a distance away from the others but on the same side of my face. It did nothing for a few days then pow, it swelled up and was red, sore and extremely painful and v v swollen. My glands were swollen and I had a temp.My dr prescribed Flucloxacillin 500mg 4 times a day, it started going down, then two days later, another one appeared, same side of my face, and is currently a little hard lump. I am so fed up. I am nearly 37, whats going on? I had a sore eye inbetween all of these lumps, and it was a little spot like thing inside my lower lid, I treated it with over the counter cream and it went.
I am petrified this is a symptom of something more serious, I have a HIV phobia, and a phobia of blood and needles, so mainly I am worried this is whats causing this. I had a check for HIV in March this year negative ( this was the 10th HIV test I've had, and I swore to myself would be the last as I was vey ill with anxiety). I know this all makes me sound like a complete nut case, but have been on the road to recovery and now this has started!!
Does anyone have any advice for me?
