First off: the most important thing is to go to a doctor to make sure that you don't suffer from nerve ailments or something degenerative that will only worsen.
I have a similar problem that I've been trying to chase down for the past year. I've been to bike fitters and physicians, ruling out some of the fundamental bio-mechanical issues that might be factors.
One physiatrist did take note that my right hamstring is weaker than my left. That was interesting to learn.
From my own experience with consults I've had, if it's happening to one leg only it's likely due to nerve compression, and not circulatory. I've been told that exercise can indeed help. I'm undergoing a regimen now that involves exercising the glutes and hamstrings. Hopefully things will improve.
What's helped me a little is this: lowering my saddle just a bit, moving my cleats back a bit closer to my heel, and concentrating much more than ever on a maintaining a level foot position as a I pedal. I've become more aware of my cadence and power output as a result.
It's still a recurring problem, but I've become better at regulating the issue.
I think that 50% of the issue is a mental problem: that is, not letting it frustrate you to the point where you don't enjoy cycling. Finding coping mechanisms and routines (including getting off the bike) to work yourself through it is key.

Yes, I do rise out of the saddle.
Yes, I do dismount at stoplights etc.
But sooner or later the condition will arise and once it does it stays or will quickly come back.
I have found that a more cushioned saddle tilted at a downward angle works best.
This leads me to believe that it is blood flow not nerve compression that is the culprit, but I may be wrong.
I am frustrated by this by this, because by 15 miles or so, the condition becomes really uncomfortable. I'm confined to <20 miles per trip.
I just ordered a selle SMP large trekking saddle from performance in the hope that the upward tilt at the rear and downward tilt of the beak
may take pressure off of the capillaries.
Any additional thoughts or suggestions will be greatly appreciated.
