Hi.. I just wondered if anybody suffers from bad lung/chest pain due to their thyroid. I have suffered with this on and off now for the past couple of years and despite chest xrays in the past its just fobbed off. (They thought it was blood clots due to a brain haemorrhage). Its so painful, im having a flare up of it at the moment but I dont bother going to the drs as it will probably be another chest xray.
