My son is a pitcher 13.9 years old. Over the past few weeks he has been complaining about a "twinge", or "shock" in the elbow occasionally during delivery while pitching. He does not have any pain in the elbow either during or lingering, and as far as I can tell no symptoms associated with LL elbow as I have studied it. He does say the "shock" lasts for a couple of seconds after delivery. He describes it as feeling like he is popped on the funny bone - that same sensation.
Any thoughts on this? It is causing him to not throw at 100% and I have noticed his velocity has backed off a bit because he is trying to prevent it from occurring. A nerve maybe?
We are very strict on his pitch counts and rest.
Thans for your input.
