question: I have this pain that manifests certain times of day in my left shoulder for 2 days. It is intensified when I cough, laugh, or cry. Sometimes the pain makes me cry. It seems more associated with my head movements than my arm. I can lift arm, no issues. When I ran last evening, it did hurt me at times like a dull ache and it is only on the left shoulder. I did some light arm exercise 2 days ago. Also have had this dry tickly cough with occasional phlegm in morning for 3-4 weeks. Is it just a muscle pulled or is it something with cough..bronchitis?
