diabetes, type 2
"I was taking 30 mg of Actos daily, and for the two weeks after I seriously started taking it, I had dull throbbing headaches to full blown migraines non-stop!  About 2 weeks into taking it, I developed a dull pain in my kidney area.  Thinking it was a kidney infection, I went to my Dr's.  We found out that it was muscle soreness...one of the common side effects.  I also gained weight. As soon as I stopped taking it, the headaches stopped,and the muscle pain is going away."
