SO, I was thrown off by the achey, sore throat stuff.
Well, I got a second blister on my let hand.
and one on my left wrist
And one on my right index finger.
I might have coxsackle virus A16, the enterovirus that causes human Hand, Foot and Mouth disease.
It causes sore throat, fever, joint aches, muscle aches, and blisters on hands, feet, tongue, mouth, etc.
The neck and back soreness are the only spooky things. There's possible encephalitis concerns if this were my disease.
Luckily, I'm feeling a little better now, but the blisters suck. It says, if this is what I've got, that I could get them on my feet and on my buttocks.
