A pulled muscle sometimes feels similar to a pinched nerve. But muscle pain is usually dull and doesn't radiate outward, while pinched nerve pain is sharp and burning and extends from one area to another. Pinched nerves can stem from pregnancy, arthritis, or injuries.

Some older adults feel cold frequently. This may result from age-related physical changes or an underlying condition. Examples of underlying conditions that might make a person feel cold include anemia, an underactive thyroid, diabetic neuropathy, peripheral artery disease, or Raynaud's phenomenon. People who experience coldness that interferes with their daily activities or sleep should talk to a doctor about it.

A 2023 study suggests regular physical activity, including walking, climbing stairs, gardening, and cleaning, may help prevent or delay the onset of Parkinson's disease in women.

Misophonia is a sensory processing disorder characterized by extreme aversion to sounds people make, such as chewing, sniffling, throat-clearing, and heavy breathing. A 2023 study suggests one in five adults deals with misophonia, which can hamper family and social life. Treatment options typically blend behavior-based therapies with medication. Cognitive behavioral therapy is emerging as an evidence-based treatment. People with misophonia can also ease sound aversions by wearing earplugs or headphones and using white noise machines.

Involuntary tics are very common, with as many as one in five children experiencing them at some point. They may be temporary or long-lasting. Tic disorders like Tourette syndrome usually are diagnosed during childhood, though sometimes this happens later.

A rapid heart rate—tachycardia—is a key feature of postural orthostatic tachycardia syndrome, or POTS, a mysterious condition that involves the nervous system and can cause a constellation of symptoms, including fatigue, shortness of breath, headaches, and brain fog, as well as pain in the chest, extremities, or elsewhere in the body. At least half of all cases of POTS are thought to be triggered by an infection (such as mononucleosis), which then spurs inflammation or an autoimmune response. Treatment includes drinking lots of water, eating lots of salt, and graded exercise training.

Long-established treatments for essential tremor, such as medication and deep brain stimulation surgery, have been joined by a leading-edge technique called focused ultrasound. This incision-free procedure aims sound waves at a spot deep in the brain responsible for tremors. While scientists study ultrasound's long-term effects, the procedure is currently used to treat shakiness on only one side of the body. Other common causes of tremor include Parkinson's disease, caffeine, alcohol withdrawal, anxiety, and fatigue.

People sometimes experience a sudden tingling or numbness in the feet or hands that goes away. But if the problem keeps occurring, followed by painful or burning sensations, this could be a sign of small-fiber neuropathy. While not life-threatening, small-fiber neuropathy should always be checked out, as it could be a symptom of something more serious.
