Experiencing head congestion, slight cold, fatigue, dizziness accompanied with heart pulpatations. when i take immune booster im ok but then it wears off and i feel sick again?

Congestion: If these symptoms have been occurring for more than a week this wouldn't be a typical head cold. A sinus infection would be accompanied by discolored nasal mucus. Because you're complaining of palpitations, dizziness, fatigue and symptoms which fluctuate, could anxiety or stress be playing a role? I recommend being evaluated by a physician and having appropriate testing. If all ok, stress manageme
