HI Thank for asking to HCM I really appreciate your concern I can understand that it must be psoriasis this is kind of chronic relapsing remitting type of disease this is not the purely ski disease the cause of this disease is not fully understood but this could be gene related disease, the management of disease is depends upon the classification that includes Topical agents, systemic agents, phototherapy, alternative treatment, for all of these you have to consult the best dermatologist and physician, take care and have nice day.
