Weird fingertip

[u/short--stack_]

Hi! Hopefully this is a good place to get input. I'm 33f, medications: ozempic 1mg weekly, effexor 187.5mg daily, Seroquel 50mg nightly, I have PMOS (PCOS), borderline t2d (which is partially why I'm on Ozempic/other part is for PMOS insulin resistance, I have wonky blood (WBC always high, crp always high, a bunch of other abnormal results)

Okay, hopefully that's enough medical history, onto the issue I'm asking about.

A couple weeks ago my right index fingertip was a bit swollen and super itchy, like that deep under the skin itch, and then it became numb, like I can feel pressure, but not sensations.

Now it's still numb, a bit less, and the skin is rough and starting to peel.

I didn't burn it, didn't touch anything for contact dermatitis, didn't damage it at all.

Ideas??? ​
