Hi TAS-MS/lupy. I have had a problem with dry skin for years, but years ago I learned something that helps: Take baths or showers in warm water and before you dry off smooth all your most itchy area with oil. I use Baby oil, but any mild oil works. Then towel dry by gently blotting. The oil seals in a protective barrier that helps keep water from escaping. I read this info in the Sjogren's Book and when I tried it the itching stopped within days. Now it has become a routine part of my bath.
Now as Lynnwood mentioned many medications can cause itching even after long periods of using the med. The only way to determine which med is causing the itching is to stop using a med for 1-2 weeks and see if the itching stops. You will need to consult with your doc before starting this because he may want to substitute a med while you're searching for a cause. Many meds that cause itching fall in the category of anti-cholenergic meds and these often have meds that can substitute. I hope this info helps! Love, Butterflake
