Hi Gonwtwindo. I used to post here but graduated to the 70's post. LOL

I have my own problems with walking, but never the ones you are experiencing. I never even heard of piriformis and had to google to understand what you were talking about. I don't think this is normal aging. You might have to go back to the neurologist or maybe physical therapy would help with this. In the meantime, keep up with those stretches that seem to be helping.

Maybe someone else will chime in who has experienced this.
