Not short of breath. I am fine hammering on the bike. Hitting my 3rd chiro visit this afternoon. Things are mich betterNot for nothing but if you are short of breath get to the hospital ASAP. This is how my pulmonary embolism started. It felt like I pulled a muscle in my ribs/back and then in the middle of the night I woke up panting in horrible pain. By the time I got to the hospital 1/2 of my right lung was shut down and it was only getting worse. Keep an eye on it.
