Diovan HCT Allergic Reaction and paralysis

My wife had a severe allergic reaction to Diovan HCT within a few minutes of taking a pill. Excrutiating back pain was followed by a general diagnosis of Peripheral Neuoscopy. Some numbness in hands, pins and needles. Worst side effect is paralysis (drop foot) in both feet, much pain and soreness, pins and needles. She went from and very physically active person to an invalid in just a couple of weeks. Medical community still working on specific diagnosis. MRI's, CT Scans, X-rays, and complete examination by neurologist have confirmed the peripheral nerve damage in both sensory and motor nerves of hands and lower legs and feet. Now waiting results of a couple of nerve and muscle tissue biopsies to see if the underlying problem can be identified. Does anyone have similar experience with Diovan HCT or of one of it's components, Lisinopril?
