Doubling over, pale complexion, tears, furrowed brows

Explanation:

Doubling over is a reaction to clench the stomach when someone is in pain. Pale complexion is a result of blood loss, fear, anxiety, dehydration/light headedness, and loss or red blood cells. Tears (depending on the context) are a way to let out emotion - both sad and happy. Furrowed brows is usually a sign of discomfort which is usually a consequence of worrying too much or crying too much, both of which require face muscles to tense for a long(ish) period of time.
