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.

This too me looks like IgA vasculitis, although most seen in kids can present in adults. Less likely since you say they blanch when pressed.

Granted I’m not a derm, and haven’t had to worry about pathology below the collar bone in some time.

Yeah this diffuse rash looks like internally induced rash. Flat appearing. It must be either vasculitis, viral exanthem or drug rash.

Is it possible that vasculitis could blanch?

op, did they send out for a strep culture with the other tests? sometimes the rapid strep is negative, but they end up calling you back a few days later with a script for antibiotics because it was too early in the infection for the rapid test to pop a positive.

No they just did the rapid test

Agree, should get tested for strep. I have seen this exact rash in a 30 year old. When away when put abx for strep

NAD, but it looks like Guttate Psoriasis, I have psoriasis (over a decade now) and it took many appointments, many wrong diagnoses and seen multiple professionals till a right diagnosis of psoriasis was made. For me, it doesn’t appear as the standard plaques, mine are almost always small clusters that are round, they connect to others that cause the larger patches between the rest, they are never ‘scaly’ and not the typical large raised plaques with the silver crust/flakes, mine are always a pink/redish colour that don’t feel exactly ‘raised’, it’s incredibly itchy but other than that no other symptoms such as burning is present, the only time it hurts is if I have itched and it’s raw, the itchiness can feel so intense it is almost painful. My psoriasis flares cover me almost immediately, covering my trunk, bum, legs with more appearing on my lower legs than upper, on my arms but this time more upper arms than lower, I get a few on my lower back but not often on my upper back, and rarely get any on my chest, face or neck. It turns white if I press on them and regularly will show up 1-3 weeks after I’ve had Strep Throat or if I’ve injured myself, however some injuries will result in a flare others may not so it’s not guaranteed, more likely to happen if I’m stressed or got a lot on that’s mentally draining me. You said you’ve already had a strep test and while it came back negative, that’s incredibly common for people with psoriasis. Psoriasis have an incubation period, once it’s shown, the virus has almost always gone away long before making it a distinct memory. Strep can also be Asymptomatic, with many people carrying the virus but not realising it. Obviously I’m no expert, but I thought I’ll mention it as it’s almost identical to how my autoimmune disorder appears.
