Januvia and restlessness

After starting Januvia, I started having severe muscle pain along the lines of lactic acid burning pain when doing anything that used my muscles. I also developed creep crawly restlessness in my muscles. I also felt like I had the flu and my sinuses were swollen and had bloody drainage. After I went off Januvia, these symptoms gradually subsided. I went back on it and after two days on it all the symptoms came back and I feel like I have the flu. My muscles scream with burning pain that is really intolerable. If I walk anywhere, I have to keep stopping an giving my muscles time to recover before going on a little further. That's it for Januvia.

severe arthritic pain, body is turning to cement, heart out of rhythm, sky high blood pressure, palpations up the back from the kidneys, vivid dreams, night sweats, swelling, cold hands and feet, sore throat, dried bloody sinus, over all restlessness, headache, stomach pains. Been on Januvia for 3 months these showed up after one month and got worse each week. Went off and started feeling better right away, still have the arthritic pain in my shoulder and arm hoping it will leave. Also still having some heart rhythm problems.
