Since last 6 months, under both my feet, the skin becomes Hard automatically and then cracks start appearing, sometimes cuts are deep. Then the dead skin (under my feet) turns dark black. Note that this is happening UNDER the feet, so not visible in slippers. I am Not Diabetic. My sugar level always stays just below the borderline (for non-diabetic people). And I also do Not have BP. I am NOT on any sort of medication whatsoever. Sometimes I apply Ointments (on the affected area) such as Exsora (of Nulife Pharma) and Pasitrex-C (of Sun Pharma). First I apply Exsora for 2-3 hrs, then I apply Pasitrex-C for 2-3 hrs. Sometimes I also dip my feet in Hot Water (more than Lukewarm). I do get temporary relief from these, but again the Cracks appear, at some other place (under the feet). My mother also used to suffer from a similar ailment, during her later years (she passed away in 2010). Is there a permanent cure to this problem? What ailment it could be? Please suggest something which can cure this problem forever. Regards, Rohit Dalmia.
