bad health problems getting worse. 15 years old. please help!

I noticed symptoms starting to appear about 4 months ago and it seems like they are getting worse very quickly.
Atleast 4 times a weak i get very bad headaches, with my head pulsing, vertigo, ringing in the ears, extreme sensitivity to noise, and i can even see the pulsing in my vision where every pulse appears as a quick blurriness or sometimes a pulse of faded vision.
But my vision is always kind of faded now. i see black dots in my vision like you do when you do not eat or drink enough water. i feel very lightheaded and sometimes if i even sit up i feel as if im going to pass out.
ever since this started my heart has been beating hard (not meaning fast). and i often have extreme discomfort in my chest with beats at random feeling like its struggling to get bloodflow or possibly skipping a beat.
A few days ago i woke up with a headache (as i have been lately every morning), but with my heart beating very hard, my head was pulsing even harder now that my heart was beating harder. i could now feel the pulse through my whole body and every beat was making my body shake.
My mom took me to the emergency room but all they did was give me migraine medicine, which helped only my headache, not the pulsing in my head.
By the time i left the ER my heart was still beating very hard, maybe even harder (this was not the first time i had experienced a hard heartbeat as i do often and more frequently but was the worst ever). While leaving my vision was extremely poor and sensitive to light and my ears were ringing with sensitivity to noise.
About two minutes after getting in the car and on the way home i lost my vision and hearing completely. my face went numb, and i had the most extreme discomfort in my chest i had ever felt. I was very cold and when i felt my face, it felt as if i had been in a freezer it was so cold. My vision and hearing slowly came back after several minutes, my heart continued beating very hard though. My vision was very fuzzy and my ears were sensitive and ringing.
My heart didnt stop beating hard all day as i was just laying down, every beat was still shaking my whole body and i could feel the pulse in my face, my parents felt my face and they said they could feel it too. Also while laying down i realized i was arching my back while laying down, like it was tightening up. i didnt think much of it but it was uncomfortable so i tried to lay on my side most of the time.
That evening i felt like everything was getting worse so i went to a different hospital again.
Once checking into the ER i was so weak and dizzy i could not walk. I still could not stop arching my back and once i layed down in the hospital bed i realized my chest was very tight like i had been working out the day before, my legs started to tighten as well. This got very extreme fast (first time i had experienced this). I could not stop flexing my whole body, it hurt so bad i was screaming. The nurse injected me with valium and it helped for a little while but the 'cramping' soon came back and this happened about 2 or three more times where they had to keep giving me more.
The whole 7 hours i was there none of my other symptoms had gone away.
Doctors do not know what is going on, it seems like they have given up. Yesterday took a four hour drive to see a neurologist but he was no help.
I noticed symptoms at first about 4 months ago but they were no where close to how bad they are now. I found myself having to stay home alot during the summer becuase of this and now it is so bad that i cannot go to school.
The headaches i get are the worst headaches i have ever experienced, i have been prescribed vicodin and sumatriptan which don't always make them go away enough to not be excruciating. They can last anywhere from a few hours to days and with them it is very hard to sleep.
About a week ago i thought i was feeling well enough to finally go longboarding with my friend. This did not go well at all, I found myself walking most of the time becuase with the activity, my heart was just beating too hard and i had the discomfortable 'struggling' feeling. I tried ignore it at first but as they kept getting worse i had to stop.
Also i have always had a very bad back, i get soreness throughout my whole back and its the worst in my neck and upper back. In my neck i get craming, stiffness, aches, and soreness.
ive also lost 12 pounds in the past 4 months, i am very very skinny. i now weigh 106 pounds

okay thank you!
i have had many tests and that is why it is so frusterating. alot of doctors are stumped when i tell them my symptoms and the neurologist i saw did not even look at my MRI or blood tests, he did not even examine me. he just said i must be stressed.
yes i am stressed, this is a very hard time for me.
and yes i have considered it many many timnes, but stress or panic is simply out of the question, i know the difference as i have felt anxious before.

first of all, it sounds like you might be in a small commuinity with crappy health providers, or you have no insurance, but this should not be the case as youre under 19 and therefore qualify for state medical. second, your mom needs to step up to the plate for you. if medical professionals arent checking you for things and just feeding you narcotics, your mom needs to speak up and say something, because these drugs dont do anything to help, they just help the drs avoid diagnosing your problems. if they try to give you drugs, your mom needs to say no, shes been given that, it didnt help, that wasnt the problem. the drs should be checking you for heart and artery problems, they should check your head, you might be gettin water on the brain, they should check your eyes, especially if youve been having dark spots. i read about that a few weeks ago in trying to resolve my own medical issues, depnding on whats going on, it can be a medical emergency. this is one of the pages i looked at

it has good basic info and links to conditions it could be. but if no one is taking your health seriously, find someone that will, because you really never know.

Hi
Welcome to the MedHelp forum!
If you use computer a lot or read a lot then the symptoms of headache, dizziness, neck pain, numbness etc could be due to compression of the spinal nerves in the cervical spine region. This can happen due to overuse of computers, work involving straining of neck, herniated disc, canal stenosis, bone disease, spondylosis, poor posture etc. A MRI of the cervical spine and nerve conduction studies may be required. Please consult a neurologist. Physiotherapy will help you and hence you should learn neck exercises to relieve neck strain. Even though you are young, get your blood pressure checked. This can also cause headache with dizziness. TMJ is another possibility. If you have been out in sun a lot or drink less of fluids then it can also be due to electrolyte imbalance or dehydration. Poor sleep patterns like sleep apnea, restless sleep can trigger a headache in the mornings. You could also be having ‘benign intracranial hypertension’ (BIH). This happens due to impaired CSF absorption. A generalized throbbing headache worst felt in the morning and last thing at night. This headache is generally relieved on standing (consistent with raised intracranial pressure). It is aggravated by straining, coughing or a change in position. Visual symptoms are common. Sinusitis is another cause of morning headaches. It can be a migraine attack too. Vit D deficiency, severe anemia and chronic fatigue syndrome are the other possibilities. All these causes should be evaluated. Discuss with your doctor. Take care!
