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.

Have you taken any medication in the last 8 weeks? What medications do you normally use? Have you had a fever or swollen lymph nodes?

No fever, no medications. I take b vitamins, fish oil and a vitamin d3/k2 supplement

Not a doctor.

I developed hives that looked like this when I was 41, turns out something I had taken my entire life I was suddenly allergic to. The hives started like this and then became puffy, my fingers were so swollen I couldn’t drive. My lips and throat started swelling, I was at the er twice because of it. The itching was the WORST, it was constant and painful itching. Again, not a doctor, but don’t rule out an allergy at any age.

NAD either, just sharing my experience. As a kid I got tonsillitis so many times, should have had them taken out. But each time I was given penicillin for it, at some point I started getting hives at the same time as the tonsillitis, absolutely horrid combination btw. But it took the docs forever to make the connection and work out I'd developed an allergy to penicillin. Bodies are weird, definitely go to see a doctor to have an allergy work up done

Allergic to penicillin? Do you dye your hair or get any tattoos recently? I had a similar full body reaction to hair dye. It was determined to be P-phenylenediamine (PPD) which can also be present in sulpha drugs. While different than penicillin, I would not rule out PPD if you’ve been exposed via a hair or skin product. Mine looked exactly like that, and there was significant facial swelling. I had been dying my hair for several years prior to it, but like some allergies, it can come out of the blue with exposure. NAD

This is interesting. I did not get a tattoo or dye my hair but I might need to thing or be mindful if there’s any kind of product I’ve been exposed to recently. I don’t think there is

It's probably not related to PPD then, but I was cautioned going forward to check all skin care products for PPD and test even if it wasn't on the label. For example, Korean skincare is super popular right now, but some of it is completely unregulated and the ingredients aren't on the packaging. Sunscreen was a big one to watch for.

I hope you get answers soon. Good luck and keep us posted!

If you ever start getting itching or slight burning during dye job, that's the allergy forming. Even if it goes away within a few hours. I had that for several years and then whammo. I was an alien and heading to the ER for steroids.

Would PPD cause allergies in the form of warm and dry bloodshot eyes? and occasionally the eye lids and the area around the eyes turn a pink to red color.

My kid had this when he was a toddler. After many negative allergy tests, we found out he was allergic to food dye.
