A healing wand would be fabulous! I totally get you on running being a very singular type of fix. There's nothing else quite like it, and this is coming from someone who enjoys all types of fitness. Nutrition can definitely help with inflammation, but you know better than anyone that sometimes structural issues need more intense measures. I hope you don't need anything invasive any time soon (if ever). Technology is moving so quickly maybe if you hold out for a little while that wand will come along after all. ;)
True you just can't beat the endorphins of running. But also can't easily fix structural damage. Probably didn't help that i landed hard on my knee a few years ago. Oh well, it's still working but i will be careful
