hello, Thanks for using Healthcaremagic. I had gone through the data you have posted. common causes for chest pain are 1) GERD: mostly epigastric burning sensation. avoid spicy foods, non veg, smoking or alcohol if any and take.tab.pantocid 40 mg 1-0-0 empty stomach for 5 days 2) muskuloskeletal : chest anywhere but more of positional or pain localised to a point. you may need to take a muscle relaxant 3) cardiac: heart attack or stable angina or unsatble angina will have chest pain but along with that breathlessness. you need to consult cardiologist 4) lower respiratory tract infection. for whcih we need antibiotics and symptomatic treatment.. chest ain as such is not related to thyroid.. Hope this helps..
