I am sorry to hear about your
pain. If you had thyroid
cancer then you should ideally get a
bone scan done to rule out any cancer in the bone. It can also be a referred pain from abdomen like stomach ulcers, acidity, pancreatitis, or from the chest like in heart attack, pericarditis, pleuritis, pneumonia, and pulmonary embolus. Please discuss with your doctor. You need some urgent tests. Take care!
