Answer 1

I always thought the whole “my knee aches when it rains” anecdote was nonsense.
This thread has helped me understand why my shattered wrist with two plates w/screws has started hurting and crunching lately.
It feels like when you need to crack your neck to relieve stress, but it can’t crack in that sense. I guess the swelling is pushing on the plates and aggravating the surrounding tendons and muscles.
