Good to hear you are getting back to working out pain free.
Sometime the piriformis can become inflamed and presses against the sciatic nerve, causing pain.
You may be walking in a position which fires things up.
Standing from a low sitting position can fire up sciatica. Try sitting on a higher seat or stool.
Have you spoken with your chiropractor or a coach about this experience?
What changed when the sciatica began?
