Is this esophageal hiatal hernia?

I have this weird uncomfortable feeling in my left rib-cage.
It feels like my stomach is pushed upwards.
Heave Breathing, it feels like its blocked right beneath my chest, i cannot breath fully through my belly (into my balls (Elliott Hulse, anyone?))
No Acid Reflux
No Nausa (if anything, only after overeating after doing some heavy sports)
No problems swallowing food
No Pain below the sternum or in the (left) rib-cage

What is it?

Since last week.

Could it be a torn diaphragm ?

I have a hiatus hernia, the only realy symptom for me is reflux, which i actually didnt recognise the feeling of at first and thougt it was all sorts of things like shortness of breath or chest pains, stress pains etc.

As far as I know the hernia itself is usually symptomless and doesnt pose a health problem, but I would go to the dr and get it checked out.
