I believe that Psoriasis is more likely to appear on your joints and scalp before appearing elsewhere. More severe case have Psoriasis all over the body. I know the Docs can determine if it is P by examining the scab.
Psoriasis can show up in one spot or many. Typically, it shows up on joints, scalp, fingers, and nails, but I do know of people that get cracked, dry skin on their feet and is part of psoriasis. Since you posted this in Sept -you probably already went to see a dermatologist and know what it is.
For those that don't know what Psoriasis (aka P)is and is reading this-
Psoriasis is a rapid growth of skin cells. Those with normal skin, technically their skin changes (dry skin that gets washed, moisturized and exfoliated) every 24 days. Where a person with P's skin changes every 7 days-this is why you see scaley skin cells. What causes P, well there are many things that can cause it. It is an autoimmune disease, and sometimes started by strep throat or stress or sometimes just because. It is also known as a heretiary disease-not contagious though. It looks red and inflammed because your body is working harder and when it is at its worst...but do not take ibuprofen as you would for any other inflammation as it only makes it worse. You can not give it to a friend or a lover. I have my own theory on what causes it and I am getting tested to see if my version of p is caused by this.
I know alot about P because I have had it since I am 14 years old and not 35.
I hope this gives you a better understanding of what p is.
Well, although it isn't on the toes for you or your loved ones...P shows up anywhere. Your fingers...even in your belly button. I am not saying that if your feet are burning and scaley that it is P, but you can't rule it out either.
I get it in my armpits and places your didn't realize you can get it..Oh, in my nose-scarey eh?
