Maybe there's something about the shape of the SEAT of your trainer that is pushing against the main nerve/artery of your leg, lessening the circulation to that leg just a bit- enough for it to cause numbness after a while. Just like when we sit on our foot and it goes numb. It could be subtle and cause the effect slowly. Can you put a different seat on it to try? At the very least, stop riding the trainer for a week to see if that is the culprit rather than something wrong with you. Seems a bit excessive to me to schedule MRI's and such if it's just something putting pressure on a nerve or vein.

Lisa, the seat is my brooks.
I have one bike, so when it is not outside with me, it is inside on the trainer. I too think I am sitting wrong and causing a nerve thing (technical, I know 
). I agree, a week off would do me some good. As for an MRI, I would not choose one ever, but I know my history and doctor well enough to know he will schedule one. I detest the things and I have had enough you would think I would be used to them. I shall try to be good and stay off the trainer and see how I feel next week. Thank you for your suggestions.

The odd bit is that it is her left leg and left arm that both are going numb when she gets off the trainer.
And it's interesting that it's when she gets off the trainer, not while she's on it.
The isolateral symptoms sound out CNS. The change from exercise to rest (off the trainer) sounds out vascular/bp related. Sensory but not motor also sounds out CNS. A pinched nerve hits both sensory and motor.
With a history of severe migraine, the vascular stuff is a juicy place to look. And with the positional stress on the blood vessels to the brain on a stationary bike (neck position not changing like it would IRL) that's another reason to look at vascular effects.
Generally the docs get all excited about this kind of symptom cluster and start hollering for MRIs, at the least to cover their @$$es. Migraineurs know the drill...Last edited by KnottedYet; 09-01-2006 at 07:20 PM.

All too well. I have had more "pictures" of my brain then I can count.
