Suggest Remedy For Black Spots On The Sole Of Both Feet

Hi. I have suffer with excess callous in the palm of my hand and sole of the feet. I use a corn blade in my palms to remove vasts amounts of hard skin, then a foot file to smooth it over. I was referred to a dermatologist and underwent a patch test, nothing was identified. I was told I had ezema. I did not agree my children have sufffered with childhood ezema and I always had my hand in oilatum, diprobase, hydrocortiszone amongst others, surely my hands should be baby soft! I was prescribed dermovate, it smoothed the hard skin around my knuckles but faded my skin, I was also given emovate to apply overnight under a cling film wrap, which keeps the skins in a semi dead wet state but it returned once dried. - have recently had the most terrible itching in the sole of my feet, I feels as if it is itching deep down inside the skin, I find myself digging at it with a cutical remove, picking at it to ease the itch. I have also developed lots of black spots on the sole of both feet. I have done extensive research and consider that I have palmer planter. I would love to have an acidic skin peel, put have been told that it can cause sensitiity, I would rather suffer that than continuosly chiselling away at my hands and feet, I sometimes go to deep and cut away chunks from my hands and feet,to the point of them bleeding heavily. It is hard to moisturise my hands,
the top layer is leathered, shiny and dark. Please help. Jacqueline
