Hi welcome to the health care magic You had acute bronchitis like presentation since one week... Your pain peculiarities mentioned by you suggest towards pain from musculoskeletal pain... Thus type of pain might be because of excess coughing, so muscular strain pain there Kindly mention about which drug you have been prescribed?? Your cough and mucus improved totally ??? Which investigations done?? Fever present just now?? For muscular pain brufen can be given for five days and warm compress applied to chest.... Take sleep in supine position Avoid strenous activities... If fever, cough still present then chest x ray needs to be done for further work up... Hope your concern solved Consult pulmonologoist for examination with keeping all this in mind
