When the weather is cold, my chest hurts and my back hurts.

After reading your instructions, I clearly tell you that thoracic vertebra pain (if you are right) and cough should be treated separately, because cough is caused by lung or respiratory infection (including throat), and the symptoms are all in the chest (chest tightness and chest pain), but there is one exception, that is, malignant tumor, which can be diagnosed by chest X-ray examination (because there is already a pathological reaction, it is impossible to find it if it is not serious). Take another blood test to find out the cause of the cough. As for the spine, ask her if she has ever suffered any trauma, including jumping from a height (shaking the spine, causing curvature deformation or direct injury) and cholecystitis \ muscle strain \ incorrect writing and learning posture, etc. Can cause back pain.

Note: Malignant tumor is only a slight possibility, so don't check and treat it according to this statement.
