Something burst in my head?

Hi all, i have been suffering with Chronic-Fatigue-Syndrome for just over 4 years now and currently taking some stuff to battle infection.

I have a problem though, last week i was quite anxious (like when you have your excited feelings) and i felt something burst inside my brain, since then i have had very poor memory, slower processing and eyesight is weird like wobbly.

I am also more weaker now, more difficulty in walking and less energy to do things.

I do not believe it was a blood clot or brain damage as i went to the hospital the next day and my blood pressure and co-ordination test was fine.

I am a bit scared i have lost my cognitive ability permanently, upsetting because my whole life is based around research.

What would you recommend I do and does this sound like something bad? Is this MS? I am waiting for a doctor appointment.

I believe that when i had the burst feeling in my head it was more like a traveling feeling of something, perhaps an adrenal burst/rush that i really felt in my head that was sharp.

This has left me with a weird tightness in my face, my eyes feel pulled backward, i cannot juggle several things in my head at once, dizziness, confusion, poor balance, feeling more tired such as feeling dozy and being more shaky.

There is a pressure like feeling between my eyes and at the top frontal part of my brain. It feels warm like a mild burning, this strange migraine does not really ever disappear.

I notice also sharpness increase when i am tired, very hungry or moving in certain directions such as picking up something on the floor. It also happens if i think too much or continued anxiety.

Any ideas what this might be and what tests i should push my doctor for?

Thank you
