###Human: I have back pain when I breathe. Why? ###Assistant: Hi. You are suffering from back pain when you breathe. You do not have the pain when you cough or sneeze. The pain appears to be localized to the upper back region towards one side. According to the age and symptoms, it can be myalgia (muscle pain). I would suggest you take a muscle relaxant like Thiocolchicoside for a couple of days twice daily. If the pain is severe, take Paracetamol or Aceclofenac tablet along with the muscle relaxant. Take Aceclofenac after having food and take the antacid tablet (Ranitidine or Pantoprazole) before taking food. Take good rest. Avoid doing any strenuous activities. It is good to avoid driving and sitting for long hours, sitting in wrong poses, and avoid using smartphones while lying down to sleep. Do a hot fomentation, and a pain relief balm or gel (Diclofenac ointment) can be applied. Take a bath in hot water, especially pour hot water over the area that has pain. Avoid taking cold foods and drinks. Avoid smoking. For a final diagnosis, you can do a chest X-Ray and an ECG to rule out the pulmonary conditions and heart-related issues respectively. You have to do them only if the above measures fail or if the pain aggravates. Please describe the nature of pain. Please say about the pain whether it is a shooting type or pinching type or dull aching. Please say whether the pain is intermittent or continuous. Please say whether you have the pain when doing a particular activity. Please explain the details about your habits. Please tell if you have the pain anywhere other than upper back such as throat, neck or chest. Please say whether you had a fever or a cold. When you had a cold, please tell whether the phlegm came out when you coughed. Please report about the posture of sleep. Please say if you have changed your position of rest recently. Please describe the details about the changed mattresses or bed recently. Please consult your doctor immediately if the pain gets worse or when you have associated sweating or giddiness or weakness.
