Hi Rusty,
Over decades of unpleasant medical adventures, I've learned to treat my many doctors as my medical team, managing their communications with each other and double checking behind them. These days when so very much is known about the human body it's impossible for one doc to know enough about the body as a whole, as they did back in the early '70s and before. That's good and bad because it leads into a world of specialists and puts the burden of being the team manager on the patient. If you are lucky, as I am, you might have a family member or good friend who can go with you to listen and learn, and help you remember to ask the right questions and interpret their answers and options. I sure hope you have someone to fill this role, because when you're ill, you are in no frame of mind to process it all by yourself.
As mentioned by the good people who posted before me, the best thing you can do is lean into it with determination and try to have some kind of fun every day... hard as that may be. I know that sounds simple and corny, but it really has worked for me. I am lucky to have side-stepped cancer in my list of ailments, but have been beaten up pretty badly with other insults to my body.
I can commiserate with you in one way. I too was misdiagnosed this October by a radiologist who must've not had his coffee when he read my x-ray, leading me to hobble around with a walker on a hip thinking it was only Muscle spasms. All the while punishing it for 3 weeks thinking I was working through muscle spasms, till the Ortho Doc got an MRI to study. He sent it to 4 of his trusted colleagues for their opinions. Now that we know it's broken in 3 places, we're planning to get it fixed next week, assuming I don't misstep and really bust it between now and then. I spent yesterday hunting down my doctors and rounding up reports, blood-work, etc. to get the green light on surgery from each one. My wife is my personal savior, making sure I get where I have to go and seeing that everything gets done and done right.
Here's to hoping we can both lean into it and push through, and have a little fun every day. That goes for all of us.
Good luck,
The Other Rusty... Rockin' Rusty!
