Diovan and muscle spasms

I have been on Doivan for a little over 2 weeks now. Sudden drops in BP, fever, sore throat, gas and bloating increased heart rate, back pain....severe muscle spasms in my feet and legs. I even went to the emergengy room thinking I was having a heart attack because of the back pain and excessive gas which caused me to feel like I had a boa constrictor wrapped around my mid section. This is a nasty little drug which I will discontinue tomorrow....back to my cozar which had few side effects, but does not control my BP completely, but this medication made me feel like I was dying!! Anyone else experience these symptoms??
