What Causes Muscular Spasms In The Rib Cage Area?

I ve been diagnosed as Type 2 Diabetic for over 15+ years now and my doctor took me off Januvia last year, but recently upped by Metformin (500mg 1 pill in the morning and 2 at night) but my glucose levels have been off the chart. When I wake up this morning my level was over 373. I had oatmeal for breakfast (so sugar, syrup or jam, just plain) & 1 cup of coffee with 2 Tbsp of SF Italian Creamer. So, I checked my levels 2 hours after breakfast and they went UP to 414! I know these numbers are WAY TOO HIGH, but my doctor doesn t come back until after the new year and I m afraid of these uncontrolled levels. I ve never had a problem with my levels until recently. I m scared and don t know what to do. I don t really exercise (and I know I should, but I have a neck injury due to work, so I m in physical therapy 3x/week) and I have a bike I can ride for 30-45 minutes an hour a day or do Yoga or Pilates DVD s that I ve bought from previous years. I need some kind of help or answer, and I know stressing out about this only adds fuel to the fire. Also, my doctor just put me on the highest dose of Lipitor (forgot the dosage). And for the pasts 3-5 months my hands have had uncontrollable tremors and I m also experiencing muscle spasms primarily in my rib cage area, but it can spread to other parts of my body as well. HELP!!!!!
