this is weird and its never happened before, but a couple weeks ago i was doing squats and i pushed out my last rep and got an amazingly painful headache around the back of my neck area. a day or two later my right side muscle in my jaw felt like i had gotten hit the night before, just really sore like maybe i pulled a jaw muscle from straining? anyway i went back to the gym a week later and while doing flat bumbell bench it happened again but not until i get into heavy weights...like an instant head/neck pain and i felt like i couldnt even hold my head up. anyway right now its been over a week since the last time it happened and my jaw hurts like hell, just the right side muscle. i guess im wondering if any of you have had this happen before or if you have any suggestions...i cant wait to get back into the gym!!! thanks
