Ear pain or ear discomfort during exercise is a side effect of a number of medical conditions -- some relatively benign and others more serious. If your ears hurt when you exercise, see your primary care physician to rule out any underlying conditions or to treat the source of the pain.
TMJ
According to MayoClinic.com, temporomandibular joint disorder, or TMJ, refers to chronic or acute pain and inflammation associated with the temporomandibular joint that connects the skull to the lower jaw or mandible. Jaw injury, bruxism -- also known as teeth-grinding -- and arthritis are some conditions that can cause TMJ. If you suffer from TMJ, exercises that put pressure on your shoulders can cause pain in the jaw, ear and surrounding areas. To prevent ear pain and other TMJ symptoms while engaging in physical activity, stretch your neck, shoulders and back for at least 10 minutes before and after exercise. Practice good form when lifting weights, and maintain proper posture throughout your workout. If necessary, avoid workouts that put stress on your shoulders or upper back.
Ear Infection
Infection of the outer ear canal -- also known as otitis externa or, more commonly, "swimmer's ear" -- occurs when water becomes trapped in the ear, MayoClinic.com says. Swimmers are at the greatest risk for developing otitis externa. Otitis externa can cause pain when exercising, particularly when exposed to water. Avoid swimming and showering for a few days to keep from irritating the ear further, and see a doctor to treat the condition with antibiotics and antifungals.
Ruptured Eardrum
A ruptured or perforated eardrum can cause ear pain or discomfort when engaging in moderate to vigorous exercise. Ear infection, acoustic trauma, flying and scuba-diving can all cause the eardrum to rupture. Because a ruptured eardrum can cause symptoms such as dizziness, it's best to avoid intense physical activity or exercises that require movement of the head. To treat a ruptured eardrum, take antibiotics to reduce or prevent infection, and avoid getting water in the ear.
High Blood Pressure
Many people who suffer from high blood pressure or hypertension have no symptoms. However, intense physical activity can induce symptoms of hypertension, particularly if you suffer from a more serious form of high blood pressure known as malignant hypertension. Malignant hypertension is a medical emergency, so if you have existing high blood pressure or are at risk for developing the condition, contact emergency services for treatment if you experience ear discomfort or tinnitus -- ringing in the ears -- during exercise.
