Hello doctor. Just wanna know if you have any idea about my current condition. I've been suffering from heart burn the past week. These heart burns crawls up to my throat and to my jaw. It lasts for 5-10 minutes. And these last 2 days, I've been suffering from pain in my lower throat near the collarbone. My ears also has been really itchy both sides. I'm 22 years old and I've been smoking since I was 15. I am just worried about my throat and also, my lungs sometimes hurt from different areas.
