I have been under a lot of stress, no question there. About a week ago out of nowhere and not having eaten I suddenly felt like I had a huge lump of something in my throat, felt lightheaded and odd and tingly and my jawbone started hurting like an absessed tooth....in a few minutes it started subsiding and after only another few minutes all was gone. I haven't been feeling good for the last few months, but assumed it was stress,can't sleep enough,and when I drink water, which I rarely do, I feel drugged. I almost always have "discomfort in my chest cavity. The symptoms seem to indicate those of a heart attack in females, but it's been a week since the incident with the lump in throat and jaw pain and it hasn't happened again, I just don't feel good.
