Please don't delay... your symptoms could be from excess bradykinin build up. There is a PD poster here that is a pharmacist and when he read about my problem, told me on a thread that he knew of 3 people in his practice who died from ACE inhibitor reactions. And my son's friend's dad ended up in the hospital when I had my reaction 2 months ago!
I had been on Lisinopril for 10 yrs, and 2 other ACE drugs before that!

My bladder thing was truly agony. Your clustering of symptoms may really be from the lisinopril. My doctor had me keep a blood pressure log (taken 3 times a day) for 2 months after this and it has been perfect since I stopped the lisinopril. That reaction was making my BP swing and go higher! I'd take my tablet at night and wake up 2-3 hours later with the most terrible pain in my bladder, and as the day went on, it would become less, then I'd take the next agony pill, and the cycle would begin again! I also had the abdominal pain too. The discolored skin I had on my arms, is finally fading now. I have about 10% of it still. It was due to the drug as well.
This whole reaction was very sneaky, and I attributed it to allergies and my arthritis. Boy, was I ever mistaken! And I am the first patient my doctor has seen with this...in her 40yr career!

I found a natural treatment for blocking bradykinin receptors. It is Bromelain from pineapples! This enzyme comes from the stems of the fruit not the sweet parts. When made into an enteric coated pill, it survives the stomach acid, and will be about 40% absorbed and get into the body, and act as an anti-inflammatory and blocker of the receptors for the excess bradykinin. I have found it very helpful. 2 tablets a day of 500mg. I could only find one source of it...LEF brand.

The capsules or uncoated tablets will not work as well.
