When nerves get damaged

People with peripheral neuropathy may experience pain, numbness, tingling, and other unpleasant sensations. Often the cause cannot be determined, so the condition must be managed by attempting to treat the symptoms.

Do you really have a drug allergy?

Many people believe they have allergies to certain medications, even though they really don't. It could be that they experienced only a drug side effect after taking a particular drug, not a true allergic reaction (which is an immune system response). Unfortunately, inaccurate information can limit treatment options. So it's best to confirm a suspected drug allergy with an allergist. That typically involves getting a simple skin test or taking a very small dose of the medication in question in the presence of a medical team.

More guidance on using the COVID-19 drug Paxlovid

Guidelines advise unvaccinated people at high risk for severe COVID to take Paxlovid (nirmatrelvir with ritonavir) soon after symptoms begin. However, a 2024 study suggests that people who are vaccinated and high-risk or unvaccinated and low-risk don't need to do so.

Spouse's heart disease linked to higher risk of depression

The spouses of people who have heart attacks, strokes, and heart failure may face an elevated risk of depression, according to a 2024 study.

Regularly adding salt to meals may raise odds of kidney disease

A 2023 study suggests habitually adding salt to food may raise the odds of developing chronic kidney disease, which increases the risks of heart disease, stroke, and kidney failure.

Cardiovascular risks soar among daily cannabis users

A 2024 study suggests using cannabis weekly may be associated with an increase in people's risks of heart attack and stroke, and the risks rise dramatically with more frequent use.

Dizziness demystified

Vertigo is a symptom, not a condition. It can make people feel lightheaded, faint, unsteady, or like the room is spinning. Common conditions causing vertigo include benign paroxysmal positional vertigo, vestibular migraines, vestibular neuritis, and Meniare's disease. People should see a doctor after a single vertigo episode to determine the cause. Depending on the cause, treatments might include medications, a canalith repositioning procedure, vestibular therapy, and cognitive behavioral therapy. Staying active, not sedentary, between episodes can help people with vertigo feel better.
