I have a number of what could be mosquito bites on my calves after working outside in my garden. Some of them appear much larger than a typical mosquito bite. In addition to itching I am also experiencing tingling sensations...almost like a mild electric shock. While I have seen a few mosquitoes recently (still too cold) it would seem to be far too many bites for the few I have seen. I am beginning to suspect something like poison ivy...though I have never seen this growing in this garden.
