I have been on Lisinopril for over a month and today was the first day that I could wear shorts. My wife looked at me and said how did you get a sunburn? I could not have gotten a sunburn because I have not been out and Anchorage, Alaska is just now warm enough to go out in shorts. The red area stops at my sock line so I pulled my socks down and the red area has not changed. It stops at the sock line and I have no idea what else it could be. I am taking Lisinopril 10 MG twice a day, one Zocor 20MG once a day and one Hydrochlorothiazide 25 MG per day
