Well I drank a TON of water after I got home. I swear I pottied my brains out so there shouldn't be a lot of toxins left in my blood stream. We'll see when I get up in the morning if my back muscles hurt. She sure went to town on them, but in a more broad stroking way as opposed to tip of the elbow kind of pressure. But don't get me wrong she definitely was applying pressure! I know why I stopped getting deep tissue massages and switched to swedish, but today I needed the deep tissue relief! I hope I don't get this bad in the future!
