I'm a diabetic on novalog I'm 61 y/o and have been on Novalog and Lantus for about 8 years. I recently have gotten severe legs cramps which are extremely painful. When these cramps occur I sweat profusely. These occur mostly at night but have occasionally occured in the daylight hours. I am on potassium and magnesium supplements and believe that these levels are at a normal range. Are severe leg cramps a side effect of Novolog?
