I'm sorry to hear this, Nanc.
I'm hoping that since it's been so soon after your surgery with your new leads, that it will subside - especially since you've had the more involved procedure of the laminectomy.

It is strange that it's only on the left side. Does it feel like a 'tightening' feeling, like a spasm? Does it come and go, or is it constant.

I wonder if your Dr will do an xray to make sure everything is where it should be.
