hum...i dont know, I hit hubby in them one time and he peed blood but the next day he was fine. LOL (he deserved it thought) ;)
LOL! No more throwing things either!!! Poor little guy... a bag of frozen peas or baggie of crushed ice might do his boys some good, too.
Yikes, I don't know! Maybe he should tell you more about his symptoms and you can go to web md symptom checker to decide if he should do something about it...
