I will try to post a couple of pictures but from looking online it is hard to tell the difference. I have scaly, dry burning patches on my hands. I have had these on my feet in the past but not currently. I have quite a few joint issues on and off so it’s really important that if it is psoriasis I know about it because of the potential link with arthritis. However most likely thing is some kind of eczema or dermatitis. It is NOT ringworm as I did a course of treatment to rule it out and it irritated it but didn’t help. Does it look anything like psoriasis?
