Any ideas? Tomorrow I have to run for 25min. in my target heart rate zone surrounded by p.e., but ever since last year, each time I do this I get a tight shooting exact pain in my left shoulder. It hurts so much that I hold to stop running and sometimes stop walking. I haven't told my teacher, and I don't have a doctor visit contained by a while.
Answers:    This shoulder pain can be as a result of your body not being used to the running after not doing it for so long in between runs (an example only).

However, because of the spasm going on for this long, I would recommend letting your doctor know what's going on. Even before doing that I would recommend letting your mom know what's going on so that she can help you keep an eye on it.
