My Experience With Migraines

Pin on Migraine in 2020

I remember my first migraine well as it was, quite frankly, terrifying. I was at school at the time, perhaps eight or nine years old, gearing up for Christmas and standing in choir practice. I remember looking at my music teacher, whod taken on the role as conductor, and she quite rapidly began to disappear as I unexpectedly lost part of my vision.

When I have one of my migraines, I lose sight in one eye. This is part of an ocular migraine, which is what I suffer from.

As part of an ocular migraine, which doctors have told me I suffer from, you lose vision in one eye for a short time, usually just less than an hour.

The experience is so hard to explain to people whove never had one, but Id best describe it as that rainbow-like shimmer you see in the petrol puddles occasionally left on the floor.

It’s a scary experience but, as I’ve come to understand that I am a migraine sufferer, I’ve slowly started to come to terms with them and what the triggers are for me personally.

I can always tell when Im about to get a migraine as my vision slowly starts to disappear. I usually hold out my arm and if the hand is missing well, then ding ding ding migraine it is! One of my worst memories was while playing the guitar and, as I looked down, my hand that was doing the strumming was no longer there.

    What Causes A Migraine

    Although migraines are extremely common, their exact cause remains unknown. It appears likely that the visual aura relates to a phenomenon called cortical spreading depression which temporarily affects electrical impulses in the brain. The pain of a migraine headache probably relates to spasm or irritability of blood vessels in the brain, which are sensitive to pain . Beyond these hypotheses, however, the exact mechanism that triggers a migraine remains unknown.

    It is often possible to identify certain risk factors that increase the chance of having migraines. A positive family history is very common, so the doctor will often ask about headaches in ones parents or siblings. Overall, migraines are more common in women than in men. In addition, a persons hormonal status can affect the pattern of migraines they experience; therefore, it is natural for a woman to notice a change in headaches and other migraine symptoms in adolescence or around the time of menopause.

    Many individuals can identify specific triggers for their migraines. These triggers include fatigue, skipping a meal, caffeine withdrawal, stress, and certain foods . For many patients with isolated visual migraines, however, the events can be very infrequent and no definite trigger can be determined.

    Stay Calm And Avoid Stress

    While it can feel stressful when you notice the warning signs of an ocular migraine, its important to stay calm and avoid stress. If you let the symptoms upset you, the stress may make the symptoms even worse and result in adding pain to the episode.

    Work to recognize and learn the early warning signs of ocular migraines so you know how to relax until the symptoms subside.

    Remember, emotional and physical stress will only make any migraine worse. In fact, stress is known to trigger migraines. If you need help staying calm, try learning relaxation skills, such as progressive muscle relaxation or deep breathing techniques.
