Hello, I work 12 hour night shift and I work 3 days for 36 hours. Last night as I was working at the computer both of my ankle s started to itch and I just reach down and scratch. I was thinking maybe mosquitoes under the desk, but I didn t see any. I looked at my ankles later and saw both legs were red and itchy and covered the area under my sock and a small area above my sock of the left leg. I am 69 years old and have had a history of veins problems and have been treated twice on the right leg. Can this be related from my treatments from several years ago for my leg vein problems? Thanks you, Jim
