Leg pain

Mia • M O M M Y 💕

I’m having this sharp pain from my thigh to my ankle when I’m sitting down. It’s on the outer right leg. It’s not sciatica because I had that while pregnant. This is is a different spot. When I walk it can’t feel it, but when I sit down it hurts SO BAD. I have a heating pad on it. Any ideas on what it could be?
