It's just this simple:
I've had issues with my lower back and when it tweaks out, I'm usually wincing in pain and sleeping like a rotisserie chicken for weeks and months until it goes away.
The fist time it went out on me a few years ago I literally got rid of my sports car for an SUV because I was sick of grimacing when I got in and out of the car.
The last time it went out, it morphed into sciatica and lingered for weeks.
So when it spasm'd literally two days before my Triathlon, my heart sank because I thought the months of training were about to go for naught. But if not for that I wouldn't have broken down and got the referral from my local tri shop to visit them.
I was able to get in for a treatment before the race and was happy to find out, while I might be in pain, the issue was soft tissue and I could choose to race. I finished my Tri and though my back was not great on the bike, I was able to compete.
I had two treatments the following week and the problem is about 95% gone after 3 treatments and within two weeks.
So I'm a believer and so glad I decided to go in and so happy I can get back to training.
I would also say that an added bonus the environment itself is really awesome, Matt and all the gang at ER are funny and fun and make "Physical Therapy" as enjoyable as it could be when you're having elbows buried into your glutes.
