Feet cramps.

No, not leg cramps, which would make sense and be something that others in the state of knocked-uppedness have actually experienced.

These are feet cramps. On the tops of my feet, not the bottoms, beginning from my third and forth toes to just below where my ankle starts. Horrific, debilitating, wake me up and make me want to scream into the darkness at 3:00 am, feet cramps.

Find a solution for THAT, Dr. Google.
