Hi Dollface, how are you?
If it's sciatica, doing squats helped me. It hurts a little, but afterwards, the pain gradualy went away.
If you ignore what's happening to you and you keep sitting down, it can get a lot worse, to the point that you could end up bed ridden and in much worse pain.
Make it a habbit to stand up every 15 minutes and do a few squats. Ask your partner or a friend to massage the area (kissing it might help too)
I hope it works, please keep in touch.
