Do I need to be seen if I can't walk with a knee injury? I think it's a torn LCL or ACL...

I would suggest not walking with out seeking futher dr. Info

I'm not a doctor or a nurse, you may want to go to the ER over urgent care so that they can get an MRI of the injured area and treat it properly and quickly all at once. Ligament tears/injuries are ER worthy! Good vibes and prayers for you!
