Hard itchy blisters on my feet,I'm close to being paranoid now, I'm scared if this is already a serious type of skin cancer or leprosy.first it was just one then it became very itchy I scratch it, it bled,I put some alcohol and cotton and ignored it, then after a year or several months I don't remember how long,I just notice yesterday it's spreading onto my feet,there's now 8 hard blisters, does anybody know what kind of skin disease is this? Please I need help. My mom just said it's an allergy I caught from our dog and won't let me see a dermatologist because she thinks I'm just being paranoid. I added an image of my feet(yes they are my feet,it's ugly right,it become dry,mostly near the hard blisters)

I don't see a picture.
The odds of it being leprosy or cancer are about as close to zero as you can get.
Allergy, bug bites (fleas, bedbugs, sand flies on a beach), and fungal infections are some of the common causes.
There are many chronic skin conditions such as eczema and psoriasis.
There's poison ivy, sumac, and oak (which you can even get when the plants appear dead in winter).
Feet can get many kinds of infections from being in socks and shoes and perspiration. Bleach all your socks, dry between your toes, walk around barefoot and get some foot powder or ointment.

Without a picture, and since it's your feet, and it itches, I'd guess poison ivy first... but who knows?

I would go to a doctor and get a clear diagnosis. As Joy stated, it could be anything. Even with a pic could not diagnose. In any event we do not diagnose AMHD.

Having problems with feet is not good. From your description it is some kind of infection.

I have the same thing! What did your doctor say?

Seems like a bite or allergy to me, Again, something that the doctor should be looking at, but yes, thinking cancer and other rare disease is a little paranoid. Do you get over excited over other normal illness and "cry wolf" a lot so that mom gets tired of hearing you complaining ?
