Some issues Dr. David Aaron Hammer, MD can help you with:

Facial Paralysis

Facial paralysis is an inability to move the muscles in the face. It often affects only one side, and it can happen quite suddenly. Facial paralysis may make one's face feel frozen or numb.

Facial paralysis can happen when there is inflammation or damage to either the part of the brain that controls the facial muscles or the nerve that carries signals from the brain to the face. Some common causes include:

Stroke, which can affect the part of the brain controlling the face and prevent those muscles from working
Bell's palsy, an inflammation of the main facial nerve
Lyme disease
Birth trauma or difficult birth, which can cause facial paralysis in babies (usually temporary)
Head trauma in which nerves are damaged

Facial paralysis is a frustrating and frightening experience, but many cases are temporary and go away on their own. Even with more difficult cases, there are treatment options available, including rehabilitation, pain management, and surgery.

Headache

Headaches are dull or sharp pains that occur in regions of the head and face. Headaches occur in many different forms and vary in location, severity, and duration. They are not necessarily a sign of an underlying illness and often resolve on their own. However, headaches can present significant day-to-day discomfort. The most common forms of headaches include:

Migraines: one of the most prevalent types of headache, migraines typically last from two hours to three days, causing a throbbing pain on one side of the head. Nausea, sensitivity to bright lights, fatigue, and blurred vision all may accompany migraines. While migraines have no known cure, medications and lifestyle modifications may ease symptoms. Avoiding behaviors that may trigger migraines such as lack of sleep or loud, repetitive noises can improve headaches.
Tension headaches: also known as stress headaches, these headaches are characterized by pain in the upper top part of the head and behind the eyes. Tension headaches are common and have no exact cause; however, certain practices may increase the likelihood of developing them. For example, wearing one's hair up in a tight hairstyle or wearing a restrictive hat can put pressure on the scalp, leading to a tension headache. Other causes of tension headaches may include alcohol or nicotine use, caffeine, teeth grinding, stress, overexertion, and eye strain. Some people find posture improvement, alternating sleeping positions, and neck exercise can alleviate tension headaches. Over-the-counter pain relievers such as ibuprofen (Advil, Motren) and naproxen sodium (Aleve) may also reduce tension-headache pain.
Sinus headaches: this type of headache causes pain in the sinuses, but may progress to pain and pressure in the eyes, forehead, and cheeks. These headaches are often accompanied by nasal congestion, fatigue, and ache in the upper teeth and may or may not be caused by sinus infections or sinusitis (sinus inflammation). Some sinus headaches are allergic headaches, which arise from allergic triggers such as seasonal allergies (pollen allergies) or hay fever, causing sinus pressure and facial pain. Other symptoms of allergic headaches include nasal congestion, irritated or watery eyes, runny nose, and sneezing. Allergic headaches may be treated with antihistamine medications such as cetirizine (Zyrtec). Allergic headaches are common during pollen season, which is usually around springtime.
Cluster headaches: these headaches occur suddenly and cause stabbing, sharp pain from one eye down to the one side of the neck. They are often referred to as the most aggravating and painful type of headaches. Other symptoms of cluster headaches include nasal congestion, droopy eyelid, and enlarged pupil on one side of the face. In the past, it was widely believed that cluster headaches were caused by a bevy or "cluster" of multiple types of headaches, such as a combination of an allergic headache and a tension headache. Medical experts now recognize that cluster headaches are a separate and unique form of headache. Cluster headaches last for around twenty minutes to two hours. They may recur throughout the period of a day or several weeks, but usually dissipate within a month. Treatment for cluster headaches includes over-the-counter pain medications such as ibuprofen (Advil, Motren) and naproxen sodium (Aleve). Prescription Prednisone can help with swelling and Verapamil may reduce pain by relaxing the blood vessels.

Living with headaches is challenging; headaches can prevent people from fully enjoying life. Medical treatment and care in avoiding certain triggers can help those with headaches begin to feel normal once again.
