Jab gives me a headache

[beenKOed]

So anyway lately i have been practicing with people and i tell them to throw a Jab and when they do and it lands i get a headache instantly for about 10 secs, and the jab is not even that strong. Does this mean i have a weak chin? Should i not try to go for boxing? A little info about me that i believe that could affecting this... I don't sleep very well and haven't for awhile. My nutrition isn't all that great, hare lately i just started eating healthy and of course i have no training. I would hate to find out that i have a glassjaw.

Go to the doctor my friend, start there anyway, jabs and 10 second headaches might go together for you, but you said lately. You could be tiptoeing around something serious. Be safe not sorry!
My sister's friend slapped her son--he was 14 yrs. and probably deserved it--breaking his jaw, turns out he had a hollow spot in his jaw. See a doctor.
