Cord compression is something to bring up to a doctor. This is not a bike fit issue, this is a neck injury from your past rearing up its ugly head.

Bikes do not make one go numb from the c-spine to the feet. Something about the positioning you were in allowed an old injury to appear, but it wasn't the BIKE that made the injury.

I strongly urge you to check in with a doctor.
