Pain While Running Or Throwing a Ball Posted: 02-21-06 15:42pm
Lately, when i've been running or throwing
a baseball hard I get pain in my lower
right back. I'm only 15 years old and I
have no idea what it could be. It's
really bothering me though because I need
to get in shape and get ready for
baseball. I can't if it hurts to run and
throw. What could this be?
