The second was Laser Spine institute it lasted 2 months.
I can echo this negative experience with Laser Spine Institute. They promise the world and go on and on about how great their treatment is because there is no cutting. They claim that the laser burns away the nerves and they won't grow back so the pain will be gone forever. Don't believe it. My wife felt significantly better immediately after the procedure but her pain returned as strong as before within 2 weeks.
They will file an insurance claim but want a large payment up front and claim that they will refund whatever amount the insurance covers. They charged us $30,000 up front and only refunded $3,000 because they filed the claim incorrectly so insurance denied all but the $3,000. They claimed to resubmit several times over 6 months to correct the filing errors. The insurance company has no record of LSI contacting them any to correct the filing - they lied repeatedly. They don't participate in any insurance plans so all services will be covered - IF they were filed correctly or at all - at out of network rates meaning you have to pay more out of pocket with a higher deductible. After 6 months we ended up having to sue to recover the deposit and for false claims of effectiveness. It was over 2 years before we were able to settle anything. In other words, we wasted a lot of time, money, and pain based on their lies. Since our suit, they've added lots of weasel words to their claims of effectiveness BUT that's only in the small print buried in the paperwork. Verbally they continue to give assurances of the miracle of laser treatment BUT it's what's in the written agreement that you have to sign that has the legally binding claims of effectiveness - ie no guarantee of any benefit at all along with a long list of consequences so that their butts are covered.
Now that that is out of the way...
My wife has had many surgeries on her back. Whatever you decide to do, if surgery is suggested by the doctor, please, PLEASE get at least a second opinion. Most insurances will pay for second opinions 100%. The 2nd or 3rd opinions can help a lot. The first doctor might recommend a procedure that is more invasive or extreme than needed.
Make sure to get opinions on the doctor from people that he's worked on before and that you trust to give you an honest opinion. There are websites that have reviews of doctors. Contact the state licensing agency and the Better Business Bureau to see if there are any complaints about him. Some insurance companies will have historical data that they will share. You're going to also have to balance all of that against your feelings about him - how does he treat you (does he talk down to you), does he discuss many options or only offer one option (probably the most expensive one), do you feel comfortable or do you get the willies.
Looking back, we wish that someone had cautioned us, had told us to not make decisions based on hope that might not be justified. It's hard to make good decisions when you're hurting so much and you just want to feel better. When someone comes along and offers you something wonderful, with great authority and great sounding claims, it's hard to not get your hopes up and leap at it.
The problem for us was that we didn't know what we didn't know. We trusted that the doctor knew best, that he was more interested in helping us rather than lining his pocket. We ended up making decisions that, in hindsight, probably weren't the best. The very first thing that was done to her was spinal fusion - a very, very bad decision but again, we didn't know any better and this was before the Internet made it easy to get information. 2 years later, the hardware had to be removed because two of the screws were loose. Today we can laugh about her having a screw loose but at the time, it wasn't funny, it hurt! That surgery was supposed to fuse 5 joints but because the hardware wasn't prolerly secured, we found out later that only two were actually fused. That surgeon would end up having his license revoked.
We didn't do the research we should have to see if the doctor was competent or if fusion was the appropriate solution. Now, too late, we know that fusion should be the last resort, not the first one. We didn't know better and he promised that it would fix her pain.
Later she would have surgery to trim spurs off the vertebrae, chemically burn the nerves away and the useless laser treatment. None of them provided any significant or lasting relief. Largely that's due to the botched fusion.
All of this DOESN'T mean that there aren't good and caring doctors out there. There CERTAINLY are. You need to do the legwork to make sure that your doctor is one. This doesn't mean that there aren't good treatments available. There certainly are but you need to do the legwork to make sure it's the right one for you.
After all this and at her age, we've pretty much accepted that we're probably not going to get something that is going to "fix" everything. What she does now is get injections every 3 months. This doesn't take away all of the pain but does alleviate a lot of it so she can function without a lot of problems. We researched and found a pain specialist who has done this procedure a lot successfully, one that was well recommended, and who treats her well and respectfully, one who she is comfortable with and trusts. As long as the injections continue to provide good pain relief, we're going to continue with them and not try any more surgeries.
One last thing, you've talked about Ron's drinking. If he does have surgery, he HAS to be sober for at least a few days before surgery. Alcohol in his system could complicate things for the anesthesiologist and you never want to do that.
I don't know if any of this is helpful. I hope that you will find someone and some solution that will help him.
