I have Type 2 diabetes for about 3 years and I am currently on Amaryl twice a day. I have very high sugar readings in the morning. My doctor put me on Onglyza 5 mg. taken before bedtime. My sugar level has gone down from the upper 180's to the 140's. During the day after meals it has been as low as the 120's which is a miracle for me. After about a month on it, I developed very painful aches and pain in my legs. The pain is so bad that I cannot walk or put any weight on my knees. It even hurts to stand at times and I can't climb stairs or function. Has anyone else experienced this symptom while on Onglyza?
