It’s not that simple.
I have a knee prosthesis, and I experience pain every once in a while, that I believe is weather-related. But it’s not like I can tell a storm’s coming. I just know when it’s gonna be a good day or not when I wake up in the morning, and it so happens that it’s more often a good day when the weather looks nice.
But it’s not atmospheric pressure or humidity. It’s just… “something in the air”. Or it’s entirely possible that there’s nothing at all in the air and there’s absolutely no correlation, just an apparent relationship.
Secondly, the pain doesn’t come from a piece of metal in your bone: it comes from neuromas on the nerves that were cut, that went to bits of you that aren’t there anymore. Same phenomenon as phantom pains in those who lost a limb, and also a fair number of people with spinal cord injury. And there’s not much you can do about it, aside from learning to deal with it over time in a pain management clinic.
Thirdly, don’t think it’s like a dull, slightly nasty feeling: when it’s a really bad day, I’ll pop pills until I’m blitzed out of my mind, and it’s only just barely dulling the pain. Thankfully, it doesn’t happen very often anymore after 30 years - maybe 2 or 3 days a year, the rest of the time it’s manageable with ibuprofene when it’s a bad day. I consider myself lucky that it’s not any worse, but I wouldn’t wish it on my worst enemy.
Get yourself a barometer instead, trust me on that one.
