I am a runner, been weight training for a while now.
For the last 2-3 days i am feeling the need to take deep breaths very frequently, and after a while not being able to do that as well.
It feels like there isn't enough space in my chest for my lungs to expand. There is no pain. No problem while sleeping as well once I find the right position.
I went to a pulmonologist but he said there's nothing wrong.
I don't understand what's wrong here, I am guessing I might have pulled my pectoral muscles while weight training, but not sure.
