My boyfriend often has 'itchy' skin, mostly on his legs and arms. It gets worse in winter. These is no rash or discolouration, but he says it feels itchy. This happens a few times a day and it's very frustrating for him. He's reluctant to see a doctor because he doesn't think they'll be able to do anything. Perhaps if I could find a possible diagnosis and treatment options he'd be willing to see someone. Help?
