[INDENT][LEFT][INDENT]Are you taking any medicines, other than the ones you mentioned?[/INDENT][/LEFT]You need to have your fasting glucose tested. Find a good, calibrated glucose meter, and you can do it yourself. Your 8 hour fasting glucose level, should be less than 110. Between 110 and 125 is considered glucose intolerant, or pre diabetic. 125, or greater, will give you a diagnoses of being diabetic. The numbers were recently shifted down. It sounds as though it could be related to diabetes, which can cause nerve damge, or poor circulation in your legs due to peripheral artery disease (PAD). If it were PAD, you would have pain and heaviness in one or both legs. There is a simple, painless test they can do to check your circulation.[/INDENT] [INDENT]You are describing symptoms of peripheral neuropathy (PN) . There are a host of causes. Some medicines, such as statins (lipitor) and fenofibrates (tricor), can cause this in some people. A neurologist would want to do many tests, probably, I can tell you. They can do "nerve conduction studies" that involve inserting very small needles into various locations, along your leg. They then monitor the response of the nerve, to a small electrical stimulation.[/INDENT][INDENT]Hope you figure this out soon, but, in the meantime, exercise (walking) is very good for leg ailments. :)[/INDENT]
