Welcome, NRivers!

You've probably had every test there is, and it must be frustrating to have no solution yet.

I agree that the eye problem might be due to dry eyes, a problem many people have as we get older. I've been treating mine for years with artificial tears and the lid hygiene measures that Atticus describes.

As for the other problems, it sounds as if you're still active enough not to feel impossibly limited by them.

I have MS, which brings on a variety of bothersome problems, including some that are hard or impossible to get rid of. After 40 years of this vulnerability to infections plus mobility limitations (and hearing and vision problems thrown in), I'm gradually learning that my body is going to do what it wants to do, and all I can do most of the time is let nature take its course.

If there's pain or numbness, there's a good chance that with time it will calm down. The catch here is that the amount of time can be considerable (many months sometimes). It's a waiting game but if a problem isn't making it impossible to sleep or eat, I try to just work around it.

Pain and numbness issues can be connected with your routine activities. If you sit a lot as I do, you might try a different type of seating arrangement or ask yourself if you're in a position too long or if the position involves slumping. All kinds of problems can be solved by just making a conscious effort to do something differently--and that goes for sleeping positions too.

I find it very hard to pick things up off the floor and yet I'm always dropping things. I keep a reacher handy for help with that--and try really hard not to drop things. Sometimes I'll leave something on the floor until I'm ready to pick it up. Not a good idea because of the danger of tripping over it.

My point is that with problems like yours, sometimes it's best to just observe them and try to figure out the cause by looking at what you're doing that might be provoking them. It might even be something you're wearing--garments that are binding or too tight, shoes that fit poorly, etc.

Since the doctors have come up with nothing, maybe you can figure out some solutions on your own.

There might even be a diet issue, or something you're taking --a a prescription or over-the-counter remedy. Even diet supplements can cause strange problems.
