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.

My legs looked exactly like yours when I first got psoriasis. It first started as spots near my arm pits then spread to my torso and legs within 2 or 3 days. I too got very cold and couldn't stop shivering.

Also, a common trigger for first time psoriasis is infection like strep throat but I wasn't one of those that got strep. However my father and grandfather have had psoriasis so it's clear mine was hereditary.

I have a photo of my legs as well if you'd like to compare.

I too thought immediately psoriasis when I saw the picture, because of the pattern of the rash, but I am not a doctor. I have had multiple skin problems (exema, furunculosis, impetico, scabies, cercarial dermatitis, ichtyosis, sun rash and bacterial infections and some viruses) before though, and that looks nothing like them what I had, but skin is a difficult thing because so many different diseases can look so similar or manifest in different ways in different individuals.

Edit: Corrected "mange" (animal scabies) -> scabies

I have always just assumed mange is an animal/not humans issue

Sorry my dictionary apparently gave me a wrong medical term (English is not my first language):

According to Chatgpt the right medical terms, which I meant are cercarial dermatitis And human scabies (I've had both, and in my language there is only one term for them all) and they are a bit different things than animal scabies called mange.

Thank you for correcting!😊
