### input:
I had a  raise in my PP glucose level ( 155)  in 2004. Since then I have no problems in my glucose level both FBS and PP. They are always within limits FBS < 100 and PP < 120. However as of November 2011, I had fluctuations in my PP that rose upto 180 after 2 hrs of food. However, all other readings like H1bc, C-Peptide levels are well within normal limits. The latest taken last October was H1bc 4.7 and C-Peptide 3.01 taken at Appolo HYD. My lipids are quite normal except triglyceride which is fluctuating between 140-180. My BP is 70/110 - 120/80 always. My weight is 70-71 Kgs. I am a male and aged 62.    The current problem is that I had cramp like symptoms in both my legs on Jan 04 2014 after an air travel lasted 6 hours. Then it disappeared after a day. Again I got it yesterday and it continues today as well. I feel discomfort at the calf muscle and a slight burning sensation on ankle area while I walk. There is no shooting pain nor tickling pain but a feeling of discomfort in both legs especially below the knee at the calf muscle. I have no pain during sleep. The discomfort starts only after I woke up form bed and start moving. Thank you

### output:

You are having a vascular claudicationhere are the factors specifically in your case)1) diabetic vascular problem - decreased blood circulation especially at the lower extremities2) calf pain at walking - this is an effect of number 1, when you walk, the blood and oxygen demand of your muscles increases, considering the fact that you already have a limited blood supply to start with BEC of number 1, you start to feel an ischemic pain (pain in any part of the body due to lack of oxygen carrying blood, the supply of your blood, cannot cope up with the increased demand of blood during walking only)3) relieved by not walking on it (decreased oxygen and blood demands of muscles, hence no pain)4) burning sensation (is a sign that a nerve is also not getting enough blood supply)here is on practical tip you can do by yourself to confirm your problem try using a stationary bike and use it for 15mins. Are the symptoms similar? If yes then that's your answer right there. You indeed have it. Next what to do. Well it's an expected part of having diabetes. Exercises strengthen muscles and train muscles to function with less oxygen and helps muscles to work better despite impaired blood flow in your legs.  As a result you will be able to do more with less pain and be more active with an overall increase in health and well-being.  Exercise will help in controlling your blood sugar and blood pressure, which will aid in decreasing your likelihood of developing more severe Peripheral Vascular disease
