Dynacirc symptoms and conditions

After being on Diovan hct 160/25 for about two years I developed a severe stiffness in my neck, a piercing center chest pain when I coughed and so much muscle/joint pain I could barely get out of bed in the morning. Don't know if it is a result of Diovan, but this is my only med. Finally (after a year) I spent six months undergoing tests and consults with one doctor who finaly gave up. A second doctor diagnosed fibromyalgia and prescribed diclofenac, which somewhat controls the neck stiffness and pain. Now, a year after the fibromyalgia diagnosis I am learning Diovan might be at fault but don't know what to do next. Any suggestions welcome!...

I have experienced several episodes of nasal congestion, post nasal drip and shortness of breath since beginning this medication, which are becoming more frequent. When I don't take it, this does not occur. I asked my doctor to change me to a different BP med but was told it was not possible to have that side effect after taking it for 1 1/2 years. She wanted me to use Flonase which is a steroid that will only give me more side effects. I hate this and am considering seeing another doctor.
