Diovan and back pain

have been on diovan for about 3 years. taking 80 mg. twice a day. have gained weight. then in oct. 2007, my doctor upped my dose to an extra 40 mg. i had noticed side effects when i first started the diovan, such as back pain, dizziness, weight gain, diarrhea. then when my dose was increased, i now have knee pain, muscle pain all over, weakness in legs, more fatigue, no energy. i have to force myself to do what i need to do, because my body is so tired. the thing that scares me the most is the weakness. not just feeling tired, but muscle weakness. has anyone experienced muscle weakness while on diovan?
thanks for any response.

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??

HAIR LOST; ITCHY SKIN; INSOMNIA; BOTH SIDES HURT USUALLY WITH URINATION ONLY; BACK PAIN; LEG CRAMPS...I SAY IT'S JUST POISON, LIKE ALL MEDS!

I started taking Diovan after trouble with Lisinop (bad cough!) and Hydrochlorozide (didn't work). At first I took one tab a day, but after a month, my BP was not low enough to keep my Dr. happy, so dosage was increased to two a day. I became so exhausted I could not get up off of the couch. I would lay there and try and will myself to get up and do the dishes or something simple. I just didn't feel like myself. Then I found myself lying in bed at night thinking about how I didn't want to go on this way and what would be the easiest way to do away with myself! Now this just isn't me! I immediately quit taking the Diovan and insisted to my Dr. that I will never take it again. Within two weeks I was feeling more normal. Now I am on Toprol, better energy level, but my feet are really sore...guess I will have to wait and see.
