The other thing that is VERY helpful, no matter the cause of falls, is to strengthen the muscles, in legs thighs and buttocks to the extent possible given your general health. And to improve your ability to balance on those stronger legs. Many of these can be done while standing at the counter waiting for something to heat, chatting on the phone or (holding a safe support) while watching TV. Here are some thing to check out.

Rest assured that all of us who are older probably have some spinal stenosis. The trick is to keep everything as strong and flexible as possible so you can safely keep moving. I had a drop foot after ACL surgery in my 40's which eventually healed with 2years of daily exercises. Doc and PT assumed a nerve was damaged when I tore up the knee, and my brain had to be retrained to take over.

Let's see if @loribmt has anything to add, as she had to rehab after a bone marrow transplant, and now is able to get out and walk miles a day safely.

Good morning! I love your comment “I know we are aging gracefully, but the body sometimes seems to be aging aggressively!” Isn’t that the truth?!? 🙄

@sueinmn had some great suggestions for increasing leg strength and asked me to join in the conversation. At this time I don’t have spinal stenosis but I did suffer spinal cord damage a few years ago, which significantly affected my walking. I felt like a toddler! With the help of my PT, as Sue mentioned, I’m back to my 20 year old self in a 68 year old body! 😅
I’ve posted a link from last year where I gave my detailed exercises. The side benefit is that it also helped reverse the osteoporosis in my hips to osteopenia by strengthening the muscles, encouraging new bone growth. Only do these if you are comfortable!

One more that I’m going to add is a good video for strengthening core and our glute muscles. All of these together can help keep the muscles around our spine strong and in good alignment for less pain. https://video.search.yahoo.com/search/video?fr=yfp-t-s&ei=UTF-8&p=glute+exercises+for+senior+women#id=1&vid=d75954b17136d9d2dcde966e5e053294&action=click

I think you also really nailed a cause of pain with the realization that certain foods can increase your discomfort. What foods have you found which cause you issues with inflammation?

You might also find that walking in water can keep up your strength without injury or pain. I went to PT, but don't have your same issues, but I do have a painful leg. Magnesium, lidocaine patches for nighttime pain help. I agree on the EMG!
