I have what looks like multiple mosquito bites on both forefingers and left forearm, though 2 weeks ago I also had a bite on my forehead & one on my cheek & one on the back of my neck, each with a day or so of the other. A month ago I had one on either leg. There has been much swelling (even looks a bit bruised around the joints) and itching - I can not bend my fingers. I went to my GP and he thought it may be a spider bite but I can t recall being around spiders since my most recent reaction (yesterday). He gave me antiobiotic, antihistimine and antiinflammatory. Although the swelling and itching improved, I had the another reaction yesterday. I do have 2 cats but I checked them for fleas,etc and nothing. My husband has no reactions to either cat.
