My understanding is that it's not the goal, but that it can occur when using graston tools, which is what we did and I've had done before. I personally feel like I bruise easily and the majority of it was on the side that happens to be more severely affected for me in regards to tightness, restriction of movement, etc. And bruising may be the wrong word as it was more pinpoint and probably petechia from the friction. I will get petechia during handstand push ups too for whatever that's worth..We used a pain scale to determine if it was too much and I was never at a point where I was unable to converse with him, so didn't feel that it was too firm at the time.Myofascial release shouldn't cause bruising... the whole point of it is very very light touch. If it is causing bruising, someone is being much too firm.
Unrelated to my PT, I was stalking a website for a collab release of workout shorts from one of my favorite companies. They featured baby unicorns holding donuts. I stalked the website, had them in the my cart, attempted to check out 3 times and got an error message. Had to go through paypal and by the time that worked, they were sold out. I'm irrationally sad about this.
**Update: And no longer irrationally sad about the shorts. They are restocking them and taking orders via a presale, so they are officially ordered. Now I just have to be patient for 5 weeks...**
