This is exactly what my m.d. told me he thought. I've had the same symptom coming on recently but it didn't get as severe as some in the past but seldom am I bothered with this. Since that time though, I have developed restless leg syndrome for which I was put on meds but I started exercising and going to bed and getting more rest and that is not bothering me so much. The biggest changes I've done is adopting a 75 lb lab and walking him multiple times a day down the court. This and more sleep seem to be the best prescription for me. I hope you get more relief soon as well.
