Mom, have you had an MRI of the spine? I haven't had one either, but my torso is numb on the right side, starting at the bra line and tapering off at the waist. I think I must have a lesion in that area.

As to your numbness getting worse, anytime I do stuff - exercise, standing up for a while, painting the kitchen... I pay for it later. Either with muscle aches and cramps, or with numbness. I feel the best when I've had lots of sleep the day prior.
