Oh im sry i see it says to put my age on here i am 37 511 and 160lbs  <response>: Hi. First, its not clear if you are having psoriasis in your groin area. It could be Tina courts too. And, phenytoin is not known to cause psoriasis in current medical literature. On the contrary, there are some works on phenytoin as a treatment for psoriasis! Here is one such paperclip:europepmc.orgabstractMED21970250Now coming to your condition, I think you should give antifungals a try. Apply On abet cream twice daily. Update us after a week. If possible, post clinical photograph for confirmation. Hope it answers all your queries
