Rash identification help
Could use some help identifying this rash. The first photo is outer thigh the first day I noticed the rash, this past Saturday. Second photo is an accompanying (maybe unrelated?) rash in the inner thigh. Third photo is this morning.
As far as symptoms, I felt slight itching and overall swelling but nothing major. Earliest I could have been bitten by anything was this past Tuesday. I'm trying to rule out: spider bite, skeeter syndrome (I usually get hives when getting bit by mosquitos, but never had SS before), and crossing my fingers it isn't Lyme. I didn't see a tick but I know that doesn't mean much. I started doxycycline this AM as a precaution, Lyme test was negative but it's early days.
Also - I didn't outline but it seems the area isn't expanding (at least since the day I noticed it- it likely could have gotten bigger from day 1, whenever that would have been). First photo was at least day 2, up to day 3 or 4 after the bite.
