Good morning! I want to suggest that it’s NOT the THING itself (stenosis) but the EFFECT of the thing which may be different for us each. So it’s not the stenosis itself but maybe arthritis, state of your spine, muscles, or an impinged nerve (as examples). Remember that people can have the exact same named problem yet they have no pain. I see this all the time. what is the stenosis doing that is causing you pain is the question to ask. Then we can offer solutions. Ihave spinal stenosis and the pain that it causes is remedied by RFA-radio frequency ablation. However, the pain which I have from generic “degenerative disc condition“ causes all kinds of destabilization, causing all kinds of myofascial problems, causing all kinds of impinged nerve problems traveling. For my case, the doctors have no solution for some of the pain my crummy back causes. I take a small dose of Percocet for 25 years very stably. when I travel the poor seat quality exacerbates the pain so I also have carried a high density foam seat cushion. the seats now are much better so I no longer need it. . The thing that I always do is get an aisle seat. I travel for work and work will only cover economy class so I book early and get an aisle seat which allows me to stretch my legs, cross my legs, extend my left leg and cross it horizontal, and get up often to go to the galley or restroom. . I keep a couple extra halves of my Percocet in my pocket and find that I must have a little boost for the long distance to remain comfortable. I try to walk in the airport before I get on the plane to wear myself out a little. I don’t drink alcohol on flights but drink extra fluids and keep myself hydrated. I keep myself warm. The worst of my pain is in my lower lumbar spine and being seated for such long hours is a killer. if you have a degenerative condition like I do the only way to travel comfortably is to remove the sensation of pain by being able to change positions, exhaust myself in order to sleep on the plane, move around the cabin, watching a great movie is helpful! (Distraction!) Good topic to cover.
