The human body is full of marvels, some even bordering on miraculous. That includes the limited ability for nerves to regenerate after injuries, allowing people to regain some function and feeling. But that wonder can turn, well, unnerving when those regenerated wires end up in a jumble.

Such is the case for a rare neurological condition called gustatory hyperhidrosis, also known as Frey's syndrome. In this disorder, nerves regenerate after damage to either of the large saliva glands that sit on either side of the face, just in front of the ears, called the parotid glands. But that nerve regrowth goes awry due to a quirk of anatomy that allows the nerves that control saliva production for eating to get tangled with those that control sweating for temperature control.

In this week's issue of the New England Journal of Medicine, doctors in Taiwan report an unusual presentation of the disorder in a 76-year-old woman. She told doctors that, for two years, every time she ate, her face would begin profusely sweating. In the clinic, the doctors observed the phenomenon themselves. They watched as she took a bite of pork jerky and began chewing.

In what may be the biological equivalent to getting struck by lightning, a very unlucky man in the Philadelphia area took a very rare bee sting directly to the eyeball—and things went badly from there.

As one might expect, the 55-year-old went to the emergency department, where doctors tried to extract the injurious insect's stinger from the man's right eye. But it soon became apparent that they didn't get it all.

Two days after the bee attack, the man went to the Wills Eye Hospital with worsening vision and pain in the pierced eye. At that point, the vision in his right eye had deteriorated to only being able to count fingers. The eye was swollen, inflamed, and bloodshot. Blood was visibly pooling at the bottom of his iris. And right at the border between the man's cornea and the white of his eye, ophthalmologists spotted the problem: a teeny spear-like fragment of the bee's stinger still stuck in place.

Updated to reflect additional information on crime and health care.

Reconsider travel to Jamaica due to crime. Exercise increased caution regarding medical services. Some areas have increased risk. Read the entire Travel Advisory. 

Country Summary: Violent crime occurs throughout Jamaica. Tourist areas generally see lower rates of violent crime than other parts of the country. The homicide rate reported by the Government of Jamaica is among the highest in the Western Hemisphere. Armed robberies and sexual assaults are common. 

The U.S. Embassy routinely receives reports of sexual assaults, including from U.S. citizen tourists at resorts. U.S. citizens report slow or unsatisfactory response to serious criminal incidents. When arrests are made, cases are infrequently prosecuted to a final verdict and sentence. 

U.S. citizens should not expect the same level of health care available in Jamaica as is available in the United States. This includes generally lower levels of emergency service response times or routine care for illness or injury. Private hospitals require payment up front before admitting patients and may not have the ability to provide specialized care. Ambulance services are not always staffed with EMTs or always readily available, especially in rural areas. U.S. citizens should bring extra prescription medication as common medications such as insulin can be difficult to obtain.

We strongly encourage you to obtain traveler’s insurance, including medical evacuation insurance, before traveling. The Department of State does not pay medical bills.

U.S. Medicare/Medicaid does not apply overseas. Most hospitals and doctors overseas do not accept U.S. health insurance. Air ambulance service to the United States can range from $30,000-50,000. Read the country information page for additional information on travel to Jamaica.

If you decide to travel to Jamaica:

• Do not attempt to bring firearms or ammunition. This includes stray rounds, shells, or empty casings. The penalties for carrying firearms and/or ammunition, even inadvertently, are severe, and can include lengthy prison sentences.
• Avoid walking or driving at night.
• Avoid public buses.
• Avoid secluded places or situations.
• Do not physically resist any robbery attempt.
• Be aware of your surroundings and keep a low profile.
• Enroll in the Smart Traveler Enrollment Program (STEP) at www.step.state.gov to receive alerts and make it easier to locate you in an emergency.
• Follow the Department of State on Facebook and X/Twitter. 
• Review the State Department’s Country Specific Information for Jamaica.
• Make a contingency plan for emergency situations. Review the Traveler’s Checklist.
• Visit the CDC page for the latest Travel Health Information related to your travel.
