I have been taking Diovan 80mg tablets daily for my blood pressure for over a year. Recently I have developed side effects "not listed" in the drugs side effects listing. Periodic severe pin/needles sensation in hands/arms/feet, light headedness, severe fatigue. This to the extent I have visited the ER numerous times just to be told there is no evidence of a problem seen in xrays, blood work, EKG, etc. Has anyone else experienced these sensations as I have ??
