fainting? please help. dont know why i faint and neither does my doctor...

[sometimesrealityhurts]

i have had all of these symptoms constantly for about 2 months now. I have actually fainted twice, both of which i was playing volleyball or at practice and exercising. It seems like i ALWAYS have a headache which has been going on for about a year now. Before i faint and when i know im going to faint the first thing is my hearing goes totally away or muffled, then i start to get tunnel vision. my hands get really shaky, i break out in a bad sweat and my chest feel like it is being squeezed so hard my breathing gets fast.  By that time if i sit down and concentrate on my breathing, which is really rapid by then, it will go away in about 30 seconds. I get the headaches, loss of balance and the chest pain a whole lot more than anything else. I have been constantly going to the doctor. i have had MRI, gone to cardiologist, neurologist, chiropractor, and nothing, but it keeps on happening. Now that my coach has said i cannot play until we know whats wrong with me, and that im not playing and constantly exercising, i havent fainted, but i still have constant headaches, chest pain, fast breathing and the loss of balance. because of whatever this is, i have been benched for my whole volleyball season which is a huge deal, and it been restricting me a lot now that every single person i know is know watching me to make sure i dont collapse. please help, i seems like my doctor doesnt really care and is just sending me on a wild goose chase. anything, honestly, will help. im so desperate to find out whats wrong.

Understand What Causes Unexplained Fainting



Fainting Symptoms, Causes & Risk Factors

Symptoms
Fainting can happen suddenly or it may be preceded by other symptoms, called premonitory symptoms. These symptoms may include:

    Light headedness
    Falling for no reason
    Dizziness
    Sweaty palms
    Nausea
    Fading vision

Sometimes, people with syncope are able to avoid fainting spells by recognizing the premonitory symptoms and then lying down or elevating their legs.

Common Causes
There are many reasons why people faint. Some causes include:

    Changes in blood pressure
    Changes in heart rate
    Abnormal heart rhythms
    Anemia (an inadequate quantity of healthy red blood cells to carry adequate oxygen to your tissues)
    Improper blood circulation
    Metabolic and lung disorders
    Standing too fast
    Exhaustion
    Emotional stress
    Pain
    Overheating
    Illness
    Some medications

Sometimes, fainting causes are harmless. Other times, they can be life threatening. Whether you have a single episode of fainting or repeat spells, seek the advice of your doctor.
