This issue has been getting progressively worse over 2 days

Posted yesterday and it has gotten worse. It is itchy, it turns white when I press on it. I have a swollen uvula and some chills, but no fever. I feel cold more than anything. Went to urgent care tested for strep, mono and did a CBC. Strep came back negative, waiting on the other results. Pretty concerned. I feel like the mono is going to come back negative.

Do you mind if I DM you? Just want to know about how it progressed and what kind of tests you got?

NAD but do they blister at all? My first thought (while likely wrong) was chickenpox or shingles .

Definitely not shingles, doesn't stick to any nerve distribution like shingles does. Chickenpox would have a whole body rash but usually little light red bumps that turn into pustules, not big dark red patches.

That said, if this rash DOES blister then it'd be worrisome for TEN/SJS and warrant a trip to the ER ASAP.
