Full body pain with weakness and breathing difficulty could be due to a viral infection, anemia, asthma/COPD flare, or other medical conditions. Check your oxygen level if possible and seek medical care promptly if breathlessness persists. Stay hydrated, rest well, and avoid self-medicating until properly evaluated.

Most headaches are due to stress, lack of sleep, dehydration, or eye strain. Rest in a quiet room and drink plenty of fluids. If the headache is severe, frequent, or associated with vomiting, vision changes, or fever, consult a doctor promptly.
