Pant leg symptoms and conditions

I AM A 71 YEAR OLD MALE I HAVE BEEN ON LISINOPRIL FOR ALMOST A YEAR, THREE WEEKS AGO MY DOCTOR INCREASED MY DOSE FROM 10MG TO 20MG THREE DAYS AGO I STARTED TO GET LEG TINGLING AND CRAMPS, THEN I BROKE OUT ON MY UPPER LEG WITH SOME BRIGHT RED SPOTS ABOUT THE SIZE OF A HALF DOLLAR, THERE ARE SMALL BLACK SPOTS IN THEM AND THEY HURT LIKE RAW NERVE ENDS, IT IS VERY HARD TO WALK WITH THE PAIN OF MY PANT LEG RUBBING AND KILLING ME.
ALSO MY WIFE IS YOUNGER THAN ME , SEX DRIVE WENT OUT THE WINDOW, I THINK THAT IS PROBABLY BECAUSE OF MY AGE. BEEN THERE DONE THAT. I AM GOING TO TRY TO GET OFF OF THAT STUFF TOO.

Limping after one month on Fosamax. After two months pain was so severe in left hip and leg that I could not climb up stairs leading with left leg. Pain upon getting into minivan,had to pull my leg up by my pant leg. Also upon getting into bed I had to pull my leg up with my pajama leg and then when attempting to lay down to sleep had worse pain in my left hip. Went off Fosamax and after three months am getting considerably more mobile with less pain. Told my doctor about it and refused to take it for osteopenia.
