I am a 26 year old man and was recently diagnosed by a dermatologist to have guttate psoriasis. Over the past 2 months, i started using a coal tar OTC cream on my face and genital area. After seeing the dermatologist who confirmed my suspicion of the paoriasis, she perscribed me two ointments that i rarely use because i have found them to be bery ineffective. I had to get a a DOT physical done for a job that i started a month ago and they found +2 blood in my urine. I'm not sure what to make of this or how worried i should be. I'm wondering if it's possible that the two are connected, seeing as the psoriasis is also on my penis and the creases in my thighs between my genital. I'm hoping that's the cause of the blood or a kidney stone or something not so severe. Any help would be greatly appreciated. Thank you in advance.
