What kind of pain do you endure?

In my mid 40's, I woke up one morning when my legs were stiff and I can't walk. There's an excruciating pain to any slight movement that can twitch my face making me scream in frustration.

I called my brother who was just a few blocks from my house to send me pain reliever. I took it and slept for 2 hours, thinking I might not ever walk again.

Surprisingly, everything was back to normal after waking up like nothing really happened.

Last year in August, my left knee got swollen and it was aspirated. Still on medication that gives relief but still painful. Been 8 months...

Sigh. I hope this ends so I can function normally.
