I searched and came up with worthless volumes.

I was on the trainer today and my left leg fell asleep. This has never happened before, although last week it began to tingle and I just thought it was the vibrations from the trainer (Cycleops magnetic), but thinking back on it, there may have been other times it was starting to go and I wrote it off as vibrations. I usually ride for about an hour, my seat is about a year old and pretty good (Avenir Chelan) I shift around in the seat to avoid this kind of thing and furthermore I have been on long rides 30-50 miles (outdoors) with no problems.

I have only had the trainer for about a month so perhaps this is just a "side effect" from vibrations?
...any thoughts? (I have good circulation and am quite fit).

Thanks.
