Approx 1 year ago my doctor did a blood workup and advised me that my A1C was 6.3 and that I should make some lifestyle changes or else I may become diabetic. I changed my dietary habits and also purchased a treadmill. I have been able to lose approx 30 lbs in the last year by reducing sugar and carb intake and briskly walking 4 miles per day on the treadmill. My very recent A1C reading was down to 5.8.
For the last two weeks, I have decided to increase my daily treadmill routine to 6-8 miles per day. I even tried a slow jog as opposed to just a brisk walk. Every since I changed this exercise routine, I am having a painless, mild vibration coming from my left thigh. It is worse when I first get off the treadmill and slowly gets weaker until I don't notice it at all. It has been doing this for two weeks now and I am concerned as to what the cause may be and if I should seek medical advice.
Any help or suggestions are appreciated.
