What should I do if my mouth swells?

In 1499–1500, Vespucci joined an expedition in the service of Spain with Alonso de Ojeda (or Hojeda) as the fleet commander. The intention was to sail around the southern end of the Asian mainland into the Indian Ocean. After hitting land at the coast of what is now Guyana, the two seem to have separated. Vespucci sailed southward, discovering the mouth of the Amazon River and reaching 6°S, before turning around and seeing Trinidad and the Orinoco River and returning to Spain by way of Hispaniola. Vespucci claimed, in a letter to Lorenzo di Pierfrancesco de' Medici, that he determined his longitude celestially on August 23, 1499, while on this voyage. But his claim is clearly fraudulent, which casts more doubt on Vespucci's credibility.
