swollen hand and arm due to bug bite

[sarah]

Hello,
3 weeks ago I was bitten on hand, on the side I had 15 lymphs taken out of and it became extremely swollen. my GP gave me 3 days of cortisone pills for inflammation, I took anti-histamines off and on but 3 weeks later, i'm still swollen. it hurts a little bit but less than at first and it has gone down a bit but still very swollen. i'm starting to worry that this could become permanent. any thoughts on this? I believe I was bitten by what is called here an aoutat, an august bug - tiny mite like creature you never actually see them but lurk in the greenery and I was bitten while weeding. they had bitten me elsewhere but only caused itching. I asked about having lymphatic massage but that was pooh poohed.
It's my right side and I'm right handed so it's a bit of a handicap.
A friend who's an acupuncturist tried a session and will try another but.....going a little crazy. I realize this is a petty problem compared with others on the site but.....would appreciate any solutions.
thanks
sarah
