Hi, I am almost 50 and started to have an itchy rash two years ago. It comes and goes. It occurs at different areas of my body. Arms, hands, feet, legs, abdomen, and so on. It seems to be intensified during my monthly cycle. Sometimes I even get some swollen parts in my body. right now I the ball of my left foot is swollen. It was not itchy though. Also the the areas below my thumbs are very itchy, red, and swollen.
