I'm feeling really worried because I've been having these sharp chest pains, especially on the left side when I breathe heavily. Sometimes it comes with a really bad headache and neck pain, plus I'm getting breathless a lot. My throat feels sore too, and I just can't seem to relax or focus at work anymore. I get tired really fast and all my energy just drains away. I spoke to my family doctor, but he just said it's work stress and my eating habits causing gastric issues. I'm not sure that's all it is. Do you think there's something more going on that I should be looking into?
