Can extreme stress/anxiety cause Reaction to both Advil/Aleve (itchy throat) & tylenol (stuffy/blocked nose & throat) all of a sudden, was ok with all?

Anxiety shows itself. In may ways. Once can mentally obsess over things that frighten the person or do behaviors to keep danger away, e.g., ritual behaviors, checking and re-checking. Physically there can be heart palpitations, shortness of breath, sweating, sleeplessness, etc. Please go to a mental health professional for help but see doctor first to rule out allergy, which can be dangerous. Peace and good health.
