Shock Wave therapy device?

Anyone purchased / use a "shock wave therapy device?

I actually had that professionally done, if we’re talking about the same thing. I had an elbow that was going bad and even consulted some surgeons. The guy that did my PRP also had a shock wave system and used it a few times before the PRP. It was a big coil, took several minutes and you just sit there with it on. Once he put a paper clip beside it and turned it on and little lightening bolts shot everywhere. He did ultrasound in the same session. Honestly I did not notice a huge difference but the PRP worked like crazy.

As in ultrasound shockwaves?
Currently having weekly treatment with it.
Very painful - over 50% of people don’t complete the treatment.

I purchased a cheaper Amazon shockwave device in addition to the ultrasound. I use it on my knees about once a week (trying to work up to twice a week). It seems to help with pain and inflammation.

I went to a clinic and tried the softwave one near me as I’m looking into getting a focused shockwave unit. Trying to heal nagging injuries that MRI shows nothing there for and exercise has not helped over the years. Here is someone on YouTube that has bought several of them including focused and radial. https://m.youtube.com/watch?v=bsCNUjq3tk4
