Hello dear I understand your concern Your pain could be due to muscle strain, costochondritis. I would suggest to consult the primary care physician and undergo chest x ray and ECG scan to rule out the cardiac and pulmonary cause. If report will be normal then doctor will provide following advise: Tablet DAN MR Tablet rantac Apply warm pad application Apply volini gel Avoid exertion that cause pain, take proper rest. You can also wear elastic crepe bandage to assist the respiratory movement. Take healthy diet and avoid stress Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
