Because, IF you've had these symptoms for more than a couple of days? It could be something 'brewing' from pneumonia or an infection or, [hopefully] just a good cold! Best to get this SOLVED and in this diagnostic process, some extra clues as to long term problems could be found.
First off? BREATHING and MOVING are good things? When it gets hard to do one or both? Let alone, eating? Definitely, it's Time to see a doc or several! Better to see them now than later, because NOW means some extra new problems can be nipped in the bud. Later means you'll only beat yourself up with the what-if's and if-only's!
We all have only one life, and one body! Treat them well now? And we'll treat ourselves easier later! IF you don't like what the docs have to say? AND you've got insurance? Second opinions CAN and DO Save Lives...it did mine.
I'm hoping that all your worries and mine come to a total NOTHING. But? Better to check it all out and get these problems 'OFF THE LIST'!
