myright,
These are my opinions only and I'm NOT a health professional. However, I am talking from age 75 and as one who was advised to undergo immediate back surgery while in the Army 40 plus years ago.
So here goes. For one, I did not opt for the surgery. I've pumped iron and been into martial arts and so on most of my life. When the agony from my first back seizure eased off, I'd had time to do a lot of thinking. What I came up with was to return to exercising but with a few changes. As an iron pumper I reasoned I probably knew a bit more about the body's anatomy and ways that it works a bit better than the average bear. My docs recommended all sorts of exercises but all of them were based on ways to stretch and strengthen the back. However!---the back, along with every other movable part of the body, functions and moves because of TWO opposed sets of muscles. In the case of the back, that means the actual back muscles which keep us straight and straighten us up. A lot of docs and others tend to overlook the equally important abdominal muscles which pull us over but also provide a huge amount of support for the back.
Accordingly, I went back to the iron but with very light routines to start and a lot more concentration on exercises to stretch and strengthen BOTH the back muscles AND the abdomen. I also got smarter---the too late old and too late smart thing--and schooled myself to NOT suddenly bend down for things and try heavy lifts and so on without thinking first. As time passed, I gained the ability to unconsciously tighten my abs for a bend over or other heavy exertion.
The result? I'm 75, in great muscular shape, no doctors, no surgery, no aches or pains, and very few limits on my physical activity. I regularly climb a 75 foot radio tower and two 60 foot phone poles I use for antennas, ride horses and cycles, hike, hunt, and serve as a special deputy with my local sheriff's dept. In other words, no physical limitations. I still pump iron (on a Bowflex) every other day for about 30 minutes and it's time well spent.
Bottom line. You can overcome 'flaky' discs and the muscle spasms that come with them. Try, really try, some varied back and abdominal exercise routines for at least a couple of months before considering surgery or other medical intervention.
My very best regards and I do know where you're coming from. Been there, done that. Old CW4
