Restless legs syndrome is considered a neurological and sleep disorder as patients feel uncomfortable sensations and strong urges to move their legs, which can sometimes be painful and often disrupts sleep. The American Sleep Association estimates that nearly 12 million people in the US have restless legs syndrome.
Allergy season can be the worst time of year for people suffering with restless legs syndrome because popular over the counter medications can make symptoms much worse.
"Patients with restless legs syndrome already have difficulty sleeping as their symptoms tend to worsen at night or with rest, but sedating antihistamines, such as Benadryl, can intensify the symptoms," said William Ondo, a Houston Methodist neurologist.
Ondo adds that some people who think they are allergic to Benadryl or other sedating antihistamines because it makes them feel hyper may have undiagnosed restless legs syndrome and recommends they consult with a neurologist.
