Are joint, muscle, and leg pain possible side effects of Protonix?

I found an article that stated that joint, muscle, and leg pain are side effectos of Prilosec. I was looking for info on Prolosec because I have been advised by a couple of Pharmacisis that I could take that instead of the Protonix I have been taking twice a day for nearly two years. I am looking for this because I am currently in the "donut hole" and find that even the new generic for Protonix too expensive. I am also being treated for chronic pain. I have been noticing for about three months now that I am experieincing a significant increase in leg and joint pain and a major loss of strength in my legs.
