question: I would like to ask what are the common cause of shoulder pain which I'm feeling now since July 2011. Can this be also related to pneumonia? I have been diagnosed with viral infection in my right lungs and after taking medications, I feel relief. But in the later months, I was diagnosed again of the same illness and at the same time, feel relief after taking medications. This time, I felt the same symptoms but now, this is accompanied with right shoulder pain and right side of my neck aches sometimes.
