It is almost like a straight line that extends from his armpit to tricep and it gets sore and then it will usually disappear as season and his conditioning get better. This year he did alot of long toss as the basketball season was wearing down.
Said his arm felt great and he was looking good with his pitching but with first varsity game he was rushing during strech and next day arm was sore..I just am not familiar with this part of arm being sore on other kids but that is where his gets sore..I have taken him to sports med docs in the past and nothing is supposed to be seriously wrong but this pain location bothers me. Like I said it usually goes away in a day or two.
