You know what they say... getting old aint for sissies.
I know where youre coming from, I started running into some of that in my mid 50's, especially with my knees, and somewhat in my hands. After a useless run of shots in my knees, I did some homework and started taking Osteo Bi-Flex, Turmeric, and Boswellia supplements, and have for a number of years now, and it seems to be doing the trick. I also notice my hands seem to be better as well. Still have some minor aches and creaks, but nothing like before.
I also think that whatever you do, dont stop doing it and try and stay as fit and active as you can. Everyone that I worked with that retired just ahead of me who just went home and sat down in their recliners and did nothing but suck down beers and a pack or two of smokes a day, were all dead within a year or so.
And dont take whatever the doctors tell you as gospel. Their drugs aint always the answer, and I swear sometimes, a lot of the problem. And after what went on with ll the covid BS, my trust level in them has gone WAY down. Dont be afraid to do your own homework and ask a lot of questions of them when you do see them. Its amazing how different the conversation is and often changes when you are well-informed beforehand.
