When to get medical help

Get emergency help now if you have chest pain or pressure, especially if it spreads to your arm, neck, jaw or back, or comes with sweating, breathlessness or feeling faint; if you vomit blood or something that looks like coffee grounds; or if you pass black, tar-like stools. Call your local emergency number. Do not rely on this app in an emergency.

See a doctor soon if food sticks when you swallow, you keep being sick, you are losing weight without trying, or you have heartburn on most days.
