That was today's diagnosis.
For the past week, it's felt like someone was trying to rip out my sternum. This morning, I went to reach for a med bottle and was basically rendered breathless by a sharp ouchie feeling in my chest. I said enough is enough, and made an appointment at the clinic (the sister clinic of my PCP's office in a neighboring city, and the only one that has weekend hours) and went in. Oddly enough, after I was checked in, someone said hello and my name. It turns out one of the nurses from my PCP's office was having her daughter seen for a sinus infection. Small world.
So I finally see the doc, and he actually knows about EDS and understands. He examined me, even brought in a nurse when he had to check my sternum! I was impressed. He told me what was up, and wrote everything down for me. I basically have to breathe deep, take pain meds so I can, and rest with heat or ice on my chest. I can do that. It's nice to have a solid answer.
And that's my day so far.
