A 39-year-old female arrives to the clinic with a diagnosis of back pain. She reports difficulty performing her job duties as a waitress in a casino due to symptoms of pain and tiredness. She has been a second-hand smoker for the past 3 years due to her job setting. Patient revealed that she had a mild fever 3 days ago which went away after taking acetaminophen—which she continues to take due to frequent headaches. She also reports onset of a cold approximately 1 week ago with current symptoms of sore throat, productive cough, and chest pain after coughing. She reports presence of sputum when coughing which turned from clear to yellowish in the last 2 days. Upon examination patient presents with normal vital signs with an O2 saturation of 94% at rest, normal ROM of all extremities and lumbar spine, and normal strength of all extremities.
