I want to thank everyone who replied! And I ESPECIALLY appreciate all the suggestions for additional treatments. I had never heard of many of them--and you can't investigate what you're not aware of. So thanks!!
I had my consultation today, and for anyone who wishes to skip to the end, we are NOT doing the procedure, and I left with a referral for physical therapy (finally!!). So it was all good.

The consultation was very informative, and we discussed more than just the Tenex. Please excuse my layperson's interpretation of the science; I am relating this second-hand. That said, I am a very experienced patient/medical
client, and the guy was not a quack.
He gave a thoughtful and balanced presentation of the procedure ("According to the company that developed it, ____, but our experience has been _____."), and explained that the ideal candidate is someone with a persistent tendon injury that has not healed on its own, with rest and other therapies, after 12 weeks. Most tendon injuries get better over time. Evidently in some chronic cases of tendonitis, instead of remodeling healthy tendon tissue, the body responds by producing scar tissue, which continues to release proteins that cause pain. The Tenex procedure uses targeted ultrasound to destroy that scar tissue. It is the same goal as open surgery, but performed with different tools and a minimum of invasion. It takes about 20 minutes; five minutes of actual time to "zap" (my word) the scar tissue; the rest is prep, topical anaesthesia, etc.
The procedure is performed by interventional radiologists, so while it is frightfully new technology, it's an extension of proven, analogous procedures, like ultrasound embolization of fibroids and kidney stones. The radiologist was frank with us and said that he's only performed about 55 of them (although he's been doing them for a year, so if he's doing one a week....), and that his patients have seen around 80% improvement (interpreted both as, about 80% of patients see improvement; those who see improvement see about 80% relief). The procedure is most effective for the elbow, although it's also performed on knees, achillies tendons, and for plantar fasciitis. (The shoulder, he said, is too complex to be read well by ultrasound, and the device is not long enough to reach deeply into the joint.)
According to this doctor, the device uses ultrasound set at a particular frequency that is only intended to destroy scar tissue, although it's his feeling that it's impossible to avoid minor damage to healthy tissue--"but the healthy tissue will heal." Thus, there is a six-week recovery time before you can resume full activity.
The other downside, of course, is that the procedure is very expensive. Most insurance plans will cover most of it, but he did suggest that if we were planning to do it this year, "you might want to get in before Dec. 31 and your deductible resets." Fair enough.
It was his description of the immediate aftermath of and recovery from the procedure that was the most persuasive part of helping us make a decision. Three days of complete rest, with your arm bandaged (and pretty significant pain), followed by six weeks of only light activity (ie, use your other arm to pick up anything heavier than a novel). There is basically no way I can lose functionality of my dominant arm for six weeks anytime in the next couple of years (I am the primary caregiver for elderly family members)! So for right now,
anything else is a better idea. We also like the idea of waiting a couple more years and seeing longer-term data and more cases.
We also discussed other potential treatments, including topical ultrasound (which I've had done on my neck by a chiropractor), lasertherapy (which our vets have done for our dogs), and physical therapy.
Anyway, the radiologist was more than happy to suggest alternatives and to refer me to physical therapy in the same hospital, and I hope to hear from them next week. So that was the big win, because as much as I love my primary care physician, this is the FIRST TIME I have *ever* been referred to a physical therapist.
...It's weird to be excited about physical therapy, right? Um.
Thanks for reading and weighing in!
