Kenny, So sorry to hear you went down buddy. Knees are a funny thing. I think generally they won't do an MRI on the spot due to scheduling and they do take time to administer. I hope it's nothing serious. Please keep us posted.
Sorry to hear dude! I had a deer take me out this fall as my knee is about 90% now but has moments of pain. Kinda wondered if a physical therapist would have done much good. But who knows. Heal well brother .
