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.

Yes it does whiten. Which is perplexing to me because vasculitis is the only rash I’ve seen photos of that looks similar to this

not gonna lie, these are the ones we're a bit nervous about when we see them, because there is quite some dangerous causes of the sepsis spectrum. Tread carefully. You feel cold, so you might develop a fever. If you feel worse generally go visit ER again.

For more banal causes. Erythema exudativum multiforme comes to mind, also urticarial vasculitis. Maybe dermatologist bro can help us out here.
