Some issues Dr. Perry Earl Zack, DO can help you with:

Depression

Everyone knows what it feels like to get the blues once in a while. But depression is a serious illness that is more severe than a bad day and lasts much longer. Symptoms of depression stop a person from being able to function and enjoy daily activities for weeks or months at a time. It can happen to anyone, and it isn't something that people can control by force of will or "snap out of it."

Some common symptoms of depression include:

Feeling sad, guilty, empty or hopeless
Fatigue and a lack of energy and motivation
A loss of pleasure in activities that were previously enjoyed
Unusual sleep or eating habits
Mental fog -- trouble concentrating, remembering, or making decisions
Physical aches and pains
Suicidal thoughts or a preoccupation with death

We don't yet know what causes depression, but it's thought that it is a combination of genetic, biological, environmental, and social influences. Because of this, the most effective treatments for depression combine medication with psychotherapy. Therapy, especially cognitive-behavioral therapy, can be extremely helpful in resolving the negative thoughts and feelings that come with depression. It gives patients new tools that they can use themselves to cope when their depression is making them feel down.

Some of the common medications used to treat depression include antidepressants such as SSRI's (Prozac, Paxil, Zoloft) or atypical antidepressants (Cymbalta, Wellbutrin). It's important to remember that these medications have different effects on everybody, and no one medication works right for everyone. Patients may have to try a couple before finding the one that works just right for them. If the first medication they try doesn't work, they should talk to their doctor about trying something else. In extreme cases where medication is not enough, electro-convulsive therapy and hospitalization may be the answer to keeping a severely depressed person safe.

Depression is a difficult illness to deal with, but it is more common than believed and there are many people who can help. With the right treatment, individuals with depression can get back to fully enjoying life again.

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.
