I've got a thing on my chest that I can't tell whether it's ringworm or Lyme disease. It looks like a bullseye but the red outer edge is raised, which makes me think ringworm, but it doesn't itch, it isn't sore, and there's this little red dot in the center, which makes me think Lyme disease. It's not blistered, it's not scaly, it's not dry or wet, it just feels like skin. But I'm going to the doctor on Friday to have them check it out. I swear, if it's Lyme disease I don't know what I'll do. If it's ringworm, how in the heck did I get it? My cat is indoors, so I wonder if fleas could bring it. If not, it's either from the water I sample at the plant here, or something I've touched unknowingly. Either way, it sucks.
