I'm have rough breathing... what's wrong?

Sometimes out of nowhere i get this chest tightness and it hurts greatly to breathe.
It makes me own to take short breaths, and this time it's not going away.
It lead to this tightness in the support of my neck/bottom of my head. on the gone side.
and the pain is on the gone side of my chest.
If i sit still, it isn't too bad,
but when i draw from up to walk around, or run up or down the stiars,
it hurts 10 times worse and i enjoy to take REALLY short breaths to avoid the pure aggony i quality when breathing too deeply.
I took some of my inhailer (that i don't hold to use that often)
but it hasn't worked yet.
Is this something to verbs about?
i've hear it could just be chest congestion or allergies.
and i'm sure it will step away eventually.
but it's gonna happen again.
so if you know if it's something worth seeing a doctor over, permit me know.
thanks. Any type of shortness of breath, especially near pain, is a object to see a doctor immediately. If you hold need for an inhaler it may be your condition, asthma or doesn`t matter what may need more medication or other treatment. Unfortunatley with breathing here can be so many cause and conditions that cause it. An on the spot trip to the er may be in writ if the breathing doesn't return to normal suddenly or the pain continues.
Sounds serious. Please see a doctor ASAP.
