Attack of the killer mosquito

Can anyone tell me the point of mosquitoes? Anyone?

Why do I ask? Because I got bitten last Monday evening, not whilst I was in the tropics, you understand, but when I was in the less exotic surrounds of my living room. The vicious little bloodsucker attacked my ankle. Whenever I get bitten by any kind of bug, my body likes to react as though I have been injected with a deadly venom, there's usually swelling, a rash, the need for anti-histamines. So, when I get bitten by an evil mosquito, the reaction is that bit more severe. My ankle looks like more like it has been savaged by a rabid dog. And why does NOTHING work to soothe mosquito bites? And before you all start going on about toothpaste/blasting the bite with a hairdryer/witch hazel gel/aloe vera/any other USELESS remedy you care to mention, let me tell you, I've tried 'em ALL. And NOTHING works.

Anyway, the upshot is that the bite has remained swollen for over a week, and also has an odd red line coming out the side of the main swelling. This worried me a bit at first, as I wondered if I had blood poisoning. A hypochondirac can't be too careful. So, I went to the docs yesterday, after a tussle with the receptionist over what consituted an 'emergency', and whether I was eligible for an 'emergency appointment', I showed the doc my ankle. After he visibly recoiled, he precribed anti-biotics and a special hydracortisone cream. So now I can't drink this week and am £12 down after picking up prescriptions at the chemist.

All this for a stupid effing mosquito bite. Oh, and did I mention it itches like a bastard?

Aaaaaaaaaaaaaaaaggggggghhhhhh.
