Welcome to Chat Doctor, pain on breathing is to be worried about you must go to your ER and I recommend doing some basic investigations to rule out abnormalities. The investigations include X-Ray chest PA view X-ray of your arm if there is nothing wrong then it is ok hope this explains Chat Doctor.
