Hello Prudence and Ann!
Prudence, there are other medications for restless leg syndrome. Have you asked your doctor if those could help? And the itchy skin, yes, I have always had a tendency toward itchy dry skin. At its worst I slather on baby oil when I'm still wet in the shower. It doesn't completely resolve it but makes me feel like I'm doing something for it.
Ann, there have been some threads in the forum recently about shoulder pain. I think it's a common problem. I had a round of it a couple years ago, and it did resolve itself after several weeks to a few months. I can't recall exactly. Have you had it checked out by a doctor?
