Hi patriciather, I also got bitten on my ankle about 3-4 weeks ago, I didn't notice it at the time, it was on a tuesday evening in the garden, by friday I was in alot of pain as my ankle had swollen up and was red & hot. I went to the doctors that day, she said I'd had a severe reaction to whatever had bitten me & gave me antibiotics as it had become infected. It has only gone back to its normal size. I think there are some nasty super bugs about, it has left me with a scar, I bought a tube of Hydrocortisone Cream which helped with the itching. I wish you well soon, I do sympathize with you as I know how you must be feeling. :-)
