During my last cross season I was having some issues with cramping on my right side- (deep & under my rib cage) I saw one physical therapist- they thought I had strained my intercostal muscle- but I'm pretty sure they were wrong, the therapy they did, helped to ease the pain-but it never went fully away. I took 2 weeks off when season was over, kind of hoping it would fix it by it's self if I didn't stress it, but it didn't. I have since switched physical therapists and my new PT believes that it is actually my diaphragm that is the issue. I can feel a knot right under my rib cage right next to the mid line of my stomach.(last set of ribs, approx 1 inch under my rib) hopefully that makes sense. He called it a spasm of my diaphragm and recommended doing some massaging in that area to break up the tissue- he showed me by putting pressure on the spot that it is most likely the problem. (It's causing me to have little stability in my right ab while running fast- which then throws off my stride causing my left arch to collapse, he showed me the chain basically) Has anyone else ever dealt with this or heard of it. I understand how to massage the area- I just wondered if there is any other things I could do to help it to get better faster.
