bruising

I played raquetball for the first time in years. I felt like a pulled an muscle in my arm near my back.  A noticed a few days later that I was bruised right where the pain was occuring.  I didn't have any contact injury.  Can bruising occur on the outside from a pulled muscle on the inside?

Why do you think that the muscle bruised is inside and you have separate muscles outside. The same muscles you see are inserted on bones through tendons sometimes also near the joint. So if you have some problem with deltoids, biceps, triceps you still have pain from inside so take some pain killers and try to rest for couple of days. If it does not heal you have to visit an orthopaedician to assess the damage you have done by playing raquet. Take care!
