For years, I have experienced intense pain in my jaw while exercising. It used to be bearable, so I ignored it. Now, however, it is hitting me earlier (maybe 5-10 minutes after I start exercising) and the pain is also very intense. I stopped exercising to make it go away - also making it easy to ignore - but yesterday I had to run for the train (maybe 5 minutes of running) - and it was some of the most excrutiating pain I have ever felt. So, it seems to be getting worse over time. I also sometimes have some numbness in my arm. It doesn't hurt at all, but it goes numb and I can't seem to do anything with it - I can't move it unless I pick it up with my other hand.
After looking online, it looks like the jaw pain (and arm pain?) could be a symptom of some kind of heart problem (maybe angina)? However, I have absolutely no chest pain, and I don't feel sick. I am fairly young (27) and a healthy weight. I don't want to bother my doctor - I've been in there a lot recently for other problems (aching joints, depression, a rash, etc.) And I feel like these are only 2 minor symptoms that will probably turn out to be nothing. Are these 2 symptoms reason to be worried about heart problems, even considering the lack of chest pain?
