Greetings ,from your explanation I would say hat you may facing issue of keratoderma which may occur alone or as a component of another disorder. In either situation, you should respond to keratolytic ointments. Some times, one has to get the ointment formulated depending upon the severity of condition and the individual response. You will have to continue using some such ointment till there is spontaneous resolutiion or till the primary disorder lasts

It can be Palmer psoriaisis. I can. It be sure until I see the rashes. Please call me or send photos using online consult option for proper examination diagnosis and treatment advice.
