i would be pleased to answer your question
The information I would be giving you is for your education only and does not necessarily mean that you have these conditions. from your description it is very difficult to pinpoint one straight diagnosis However , I can inform you on the possibilities of the conditions .
These include: Psoriasis
, Eczemas, contact dermatitis
, starting callous .
You will surely need to see a dermatologist
to come to a diagnosis . Till then you can apply a cream called fucicort available at the chemist. Also do apply a lot of moisturizer ( Neutrogena Intensive hand cream)
Thanks and take care
