I didn't mean to leave you all hanging like that. I've been out of town. I'm happy to report that my arm is still attached to my shoulder, and it looks like my skin is not going to rot away. I am still in quite a bit of pain off and on. My dad has assured me that these bites do not look like spider bites, and he is of the opinion that the bites and the muscle ache in the same region is just coincidence. I've been told to "buck up".
I still don't know what bit me - these are certainly not mosquito bites. We'll see what happens. I am either in need of a doctor, or a week at a spa with daily massage - neither of which is going to happen today.
