Constantly sick, never seeming to get better

Patient: I have been sick now for almost three months off and on. I have never had a strong immune system, but lately it seems like I’ve been getting literally every disease that comes my way. I always eat healthy and exercise. Also, I’ve had a sore throat almost the whole time. I’ve had strep, various colds, and the flu all in this period.

Symptoms: Sore throat, dizziness, feverishness (sometimes), cough
