Weasing on exhalation, Pain under my lleft arm,when coughing or lifting my arm over my head,concerned it might be pneumonia.Began as a pain under my left arm on Thursday September 29th today besides the exhalation weasing, there is some nasal discharge.Pain like the flu - muscle aches, but have had very little exposure to any populations of people. I have been taking Advil 2 or 3 200mg every six hours. Start low and if more pain control is neede I take 3 advil. I also have complications such as MS .Thinking I should go to the doctor tomorrow , unless an ER would be indicated. Feeling rather lousy.
