itchy eyes, skin, and hair. No blisters. I do have a dry scalp causing flakes, and it is winter. The itchy scalp is really bad. Masturbate once, maybe twice a day and suffer bipolar/anxiety issues. Medication depoke 1000 mg, welbutin 150mg, daily, and trazidone when needed for sleep. What could cause itching. Could over masturbation cause pain inside of penis to be sore?
