Low Pressure Headaches Symptoms

Thursday, June 9th, 2011

What are the symptoms of low pressure headaches?

The classic symptom is a headache that becomes severe when the patient is upright and quickly disappears when the patient is lying flat. Thus, the headaches are typically absent first thing in the morning, and start or worsen shortly after getting out of bed. The pain is often worse at the back of the head, and may be accompanied by some neck discomfort and nausea. Rarely there are more serious neurological symptoms caused by stretching nerves or the downward displacement of the brain.

Ways of Treating Visual Migraine

Monday, April 26th, 2010

Visual migraine is a type of migraine known also as ocular migraine and ophthalmic migraine. Similar to the common migraine, its cause is vascular; that is, it involves the blood vessels. Whereas the typical migraine affects the arteries located in the surface of the brain, it affects the veins that supply blood to the vision center.

During a visual migraine episode, the sufferer experiences visual disturbances that typically last for fifteen to thirty minutes. It usually starts as a shimmering light with a semi-circular shape and jagged edges, seen in the peripheral vision and later expands to become more central. The ability to see is obscured within the jagged area. A headache may accompany the disturbance but does not occur in all cases. The more common symptoms that come with this are nausea and vomiting and a heightened sensitivity to light. Although the root cause of this particular migraine is not known, some of its common triggers are identified as fatigue, depression, dehydration, eyestrain, stress, alcohol, certain foods, and a shift in estrogen levels.

Diagnosing visual migraine may require visits to the ophthalmologist and neurologist. This is to make sure that the visual disturbances are not caused by an underlying eye condition such as a detached retina or a blood clot in the brain. Once this has been established, then proper treatment can be provided.

Certainly, this is not fatal nor does it cause any damage to the brain or eyes. And since no pain comes with it, treatment is usually unnecessary unless a headache arises during an episode. However, if the attacks are frequent, medications may have to be administered. If the visual migraine occurs with a headache, over-the-counter medicines like ibuprofen and naproxen can be taken to relieve the pain. In addition, non steroidal anti-inflammatory drugs (NSAID) and aspirin are known to prevent these migraine attacks because they help keep the arteries in their normal size. Medications should be taken as soon as the first sign of the aura is felt. During the attack, the vision may be so hampered that doing other activities could be impossible. In these times, the patient should relax and wait for the said migraine to end. Bright lights and sounds should be avoided because they could potentially worsen the symptoms.

Having a visual migraine attack, though most of the times painless, can be frightening, especially for those who experience it for the first time. If anyone encounters any of the symptoms associated with this type of migraine, he should consult his physician immediately. This migraine, by itself, usually requires no treatment but the symptoms could be signs of a more serious condition. Knowing about a disease and how to deal with it is the best treatment of all.

Symptoms of Ocular Migraine

Wednesday, April 7th, 2010

The symptoms of ocular migraine can also be classified as migraine auras. A migraine aura is a definite sign that a painful migraine headache will follow. It is a symptom that let migraine sufferers know ahead of time that a headache is about to manifest itself. Some people will have “pre” symptoms for a couple of days that will signal them that an agonizing headache is on its way.

Aura effects can develop for about 6 minutes and generally can appear from twenty minutes to an hour before the start of a headache. They are evidence of what used to be called “classic migraine”. Currently, medical practitioners came up with a more scientifically accurate term, migraine with aura. Only less than 20% of migraine sufferers consistently experience any kind of aura before a headache begins.

Symptoms of ocular migraines – aura effects

Most migraine auras can be seen with the eye (visual). These effects are called positive visual phenomena because rather than their vision gets hazy or goes dark, people who see them experience the following:

* Halos or Auras – an atmosphere of light, dust or smoke surrounding objects, specifically light objects.
* Floating or Flashing Lights – these can be colored or white spots that appear to move.
* Lightning Bolts – a spiked or zigzag line that flickers and/or arcs over the field of vision; with the regularity and intensity increasing over time until the person can no longer see; this light show usually ends with the beginning of headache pain.
* Photophobia – a severe sensitivity to light; this light effect repeatedly lasts the extent of the headache.

Most aura episodes last less than an hour. Migraine sufferers who experience auras that last more than an hour are told to suffer from migraines with continued aura. In some cases you may experience aura effects without developing a headache, but it’s still believed to be a symptom of chronic migraines. At different times you may experience all three variations, migraine with aura, migraine with extended aura, or a common aura without the headache.

If you’re one of the 500 million people worldwide who suffers from the agonizing pain of migraine, you should definitely consider using natural migraine remedies because common medications ONLY HIDE the symptoms for a while.

Eyesight Improvement for Headache Relief

Monday, December 21st, 2009

Eyesight improvement is achievable. You can learn to see without glasses and be relieved permanently of the pain and distress so frequently associated with defective sight. But you cannot do it by magic.

Central Fixation

The retina is a sensitive film on which the picture falls. But there is one point on the retina where the vision is perfect; that is the Macula Lutae, a point only one-sixteenth of an inch in diameter in the very center of the retina. When we focus at this point we have what is known as central fixation and our vision is perfect.

If you have lost the capacity of central fixation you are seeing with Eccentric fixation which often causes headaches, fatigue, pain or discomfort of some kind, such as twitching of the eyelids or the eyeballs. This twitching, by the way, can be stopped by pressing the sides of the base of the nose as high as the inner canthus with the forefingers of both hands, avoiding any pressure on the eyeballs. Continue the pressure for several minutes, with the eyes closed, and you will obtain relief.

One way of checking on whether you are seeing by central or eccentric fixation is to look at a word on this page. Do you see it most sharply where you are looking or do you see it better when you look a little away from it? When you look at the top of a printed letter do you see the bottom of the letter more clearly than the top? If so, you have lost central fixation.

If you are to see, you must bring your mind to bear on what you see. Because the eye can focus sharply and is at its maximum power only on a very small area at a time, an attempt to see a larger area results in a blurring of physical vision and a lack of mental focus. Teach yourself to look at what you see, to watch one tiny area at a time. For when the central fixation is perfect, the eye sees perfectly.

Think About What you See

For significant eyesight improvement, give the object you are looking at your mental as well as your visual attention. The more clearly it registers on your mind, the more clearly it will register on the eye.

Test this out for yourself. In the room where you are sitting there are probably a dozen objects which you no longer “see” because you are so accustomed to their presence that you are no longer aware of them. Look at each one in turn, not staring, but with quick, easy glances, thinking about what you are regarding. That doorknob-could you have described it before? Now you know its approximate size, contour, the material of which it is made, its relative position on the door, because your mind and not alone your eyes observed it.

Even such a familiar phenomenon as a moving picture gives us what we believe we see rather than what we actually see. A series of still pictures provides us with an illusion of movement.

See a Small Area at a Time

Instead of staring, trying to take in a whole picture at one time and thus defeating the object of central fixation, look at one small part of the picture, shift your gaze to another small part, and another, blinking naturally all the time. The smaller the area, the more clearly you will see it.

People who have acquired bad seeing habits always try to increase their area of vision by staring, which defeats its own purpose. Staring not only causes muscular tension but a lowering of vision. You can test this for yourself by staring fixedly at an object or a word on this page. After a few moments of this effort the letters lose their sharp clarity and become blurred.

Eyesight improvement can be achieved with consistent time and effort!

What Are The Causes of Headaches?

Friday, March 20th, 2009

The vast majority of headaches are non-malignant and self-limiting. Some common causes of headaches are said to be tension, migraine, eye strain, dehydration, low blood sugar, hyper mastication and sinusitis. In addition, we have some very rare headaches that are a result of some life-threatening conditions like meningitis, encephalitis, cerebral aneurysms, exceptionally high blood pressure, and brain tumors. If head injury is the cause of a headache then the reason is usually quite evident. In women, a large percentage of headaches are caused by their ever-fluctuating estrogen levels during the menstrual years. This can occur prior to or mid-cycle.

If anyone over the age of 50 experiences a headache for the first time, a condition called temporal arthritis may be the cause. Headache symptoms include impaired vision and pain aggravated by chewing. Because, there is a risk of becoming blind, it needs to be promptly treated by a doctor.

Brain aneurysm, brain tumor, stroke or TIA, and brain infection like meningitis or encephalitis are some rare causes of headaches and can be serious.
