2018 son is playing with wood bats this summer (bats right). He has developed some swelling in the soft tissue between the thumb and forefinger of his right hand. It really hurt after he hit one off the handle and seemed to swell up. The swelling went down overnight and he felt fine. Today he threw and hit off the tee - that felt fine. Then brother pitched to him and again, when he caught one off the handle, the pain came back. More than just the normal sting.
Has anyone used this product? ProHitter Batting Grip Aid Does it help?
