What details did the patient provide regarding their chief complaint and symptomology to derive your differential diagnosis?

The patient provided details regarding their chief complaint of fatigue along with additional symptomology such as muscle aches and joint pain. Based on this information a differential diagnosis was formulated which included various possibilities ranging from viral illnesses like influenza to autoimmune conditions like rheumatoid arthritis. Additionally, further inquiry into other potential symptoms such as fever or weight loss could help narrow down the list of possible diagnoses.

In order to differentiate between these possibilities, diagnostic tests such as bloodwork or imaging studies may be required in some cases for confirmation. Ultimately, by carefully listening to the patient’s reports of their experiences combined with an understanding of diseases and conditions affecting similar populations it is possible to develop a list of likely explanations that can later be narrowed down through further testing if necessary.
