Night before last I got bitten in the night by a mosquito I think. Since then it's got bigger and is now about the size of the top of a mug. A hard round swollen hot area. It's itching and sore as well as hot. I know you can't take piriton when pg but should I take anything else or put anyhing on it? Or just leave it to sort itself out?
I use an antiseptic cream, it usually sorts it out. Mark the edges of the jump with a pen, so you will know if it spreads, and if it does get worse, you might need to see a doctor. Mosquito bites can be very nasty.
Have you tried the clicker thing you get from boots etc.. You put them over the bite and click and it sends a small electric shock through the skin. Sounds mad I know but apparently it does something to reduce the immune response to the bite. Ive got one and it does work. Ive also painted clear nail varnish over bites as this stops the itching.
Could it be a tick bite? I think you should go and see a doctor asap because the circles you describe could be a 'bull's eye' rash, typical of Lyme disease. (I am just saying this as a possibility, I am not diagnosing you over the internet)
When I worked on a summer camp in the US, where I was literally eaten alive by mosquitos for 3 months at a time, they used to cover me in meat seasoning that contained all kinds of stuff that tenderized meat...Sounds utterly barmy I know, but it really did make a difference (or else the comedy of the situation distracted me from the ridiculous itching!).
Something to do with chemical reactions...i'm an accountant, not a chemist!!!
