I'm in that club too, BuickBoy! L5 seems to be a favorite spot! Mine is Spondy with a spinal stenosis kicker, which means the tail bone is closing up and curling in! Tens is very irritatiing to me, but I'm strange that way, it sets me through the ceilling. The only person that seems to be able to use a tens with me was the acupuncturist, it was hooked onto the needles. I really just would rather have heat.
You know it's all what works for you, ice is OUT for me in genereal, though I have done the 10 minutes of strong heat followed by 10 minutes of ice trick used by DC. Just don't get the heat too strong that it burns you.
My entire spine is inflamed but the SI and tail bone are the absolute worst, have degeneratove facet and disc disease too. You look so hard and long for a diagnosis, and when it starts to come it knocks you flat!!
I encourage you to take the biologics, the only thing so far that has given any relief without being Opana'ed out!!You are young, with dear little kids, you don't want to have to start riding on that train if the tens works for you, I only recommend narcotics when the pain is intractable, not as a way of life, but that may come to pass eventually too.
I have been to 3 surgeons, a local, Johns Hopkins, Univ of MD, saw the top guy each time, and these surgeons told me that surgery would only ever make me worse, if I kept looking, would eventually find one and be in real trouble. There are cases and exceptions to the rule, but unless surgery is your only means, stay away from it. It only weekens 2 other spots where the screws will go, this wisdom is from my DC, he only recommends for the worst spines he has ever seen!
Like lamb and Rich have told me stay away from the quick fix shops. No such thing, yes, I had hoped too, but was straightened out about that. There is no magic pill or fix.
The biologics are the drug of the future, take a look at them, they work differently than the usual chemical medicine. They are really quite amazing, they target where they need to go right to the very cell, and many are going through long waits of trial and error chemical drugs to get to these, they are considered the life changers.
Good luck to you my friend, ask away, we will all help you in any way we can, as much as we can, and wish you the very best always.
