Lisinopril and upper leg

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.

I started lisinopril 2 weeks ago for hypertension and yesterday developed swelling to my abdomen and left upper leg that it is tight over my knee and difficult to bend. I know it is a side effect to this new med since I usually swell a little on my right knee from overuse after I had a meniscus repair a few years ago and if it was from too much sitting or standing the right knee would have been the first to swell. It is too bad that this side effect developed as the medication really helped my blood pressure initially but now I feel so bloated.

I have been taking Lisinopril for about 2 months now, I haven't experienced any of the side-effects until recently I started waking up with numbness on my left upper leg. Overall I get weird sensations, mild numbness & tingling on my arms, fingers and feet. Thanks to this site, I realized my overall changing sleep patterns and numbness can be attributed to this medication. I will call my doctor to see if I can stop taking it. On a side note, my BP is definitely lower. I am 29/male.
