What Do Swollen And Itchy Feet Indicate While On Flomax, Crestor And Viagra?

Question : Hi. I am a 63 y.o. male. The tops of my feet are swollen, red, very itchy/scaly and have been that way off and on for over a month. The bottoms and sides are not red or itchy. Just the tops. The left foot is worse than the right and the swelling comes and goes throughout the day. I injured my left foot a month or so ago (soft tissue) but my orthopedic physician told me that the pain should resolve in a few weeks. I wrapped the left foot after I injured it with an ACE bandage over my sock and left it on for 14 hours wile I traveled and when I unwrapped it the top of my left (injured) foot had blisters and redness which scabbed over and has now healed. I take two Aleve morning and night. Also taking Lotrel for BP, Flomax for prostrate, Crestor (5 mg) and occasional Viagra 20. No other health issues other than hypertension which is controlled and my enlarged prostate. Labs as of a month ago are normal although my doctor mentioned that kidney function seemed to be slightly lower than normal.
