Knee soreness symptoms and conditions

I was a very healthy 59 yr old, who, as a result of a leg and ankle fracture and slight decrease in dine density, was placed on Fosamax Plus. I have been taking it for two and a half months and have certainly noticed many of the symptoms mentioned. I continue to experience extreme muscle stiffness- not unlike symptoms of the flu, dizziness, stomach nausea, bloating, loss of sleep (so much so that I was then prescribed sleeping pills!), bruising that won't fade, knee soreness, lower back and hip pain!
I tolerated all the symptoms because I thought many of them were associated with my injury. After the ABC 7.30 Report, I am very concerned and would like to know the long term implications. Thankfully I have only been taking Fosamax a short time but it is now in my system.
The pharmaceutical company has a lot to answer for.
