I got out of the house this morning on my way to get an MRI. I saw an arthropod!
As for the MRI, I don’t know. I fell asleep during it, in spite of the obnoxiously loud industrial music hammering through the headphones. It might be a few days before it’s analyzed and they can tell me what’s going on.
The good news is that the pain is greatly diminished, replaced with soreness and fatigue. I’m mainly feeling like I need to lie down and sleep while the cartilage/ligaments/whatever carry out repairs.
