Hello, my mother is 80 and somewhat suddenly been experiencing body aches, knee & wrist pain and fatigue. She has had the body aches for a few months, and the knee/wrist pain for a month or so. She has a bit of arthritis in her hands, but can barely lift a glass since these aches have started. Her knee and foot are swollen, also. She has had unexplained hives on and off for a few years. Her doctor had her taking Prilosec and Zyrtec for it. She used to take Fosomax, but hasn't in at least 5 years. Any idea what is going on? Her doctor isn't very helpful. Thanks for your time.
