Occiput pressure, imbalance, weird sensations (very rare pain)

[Shahmario]

20 year old, Male
I have this pressure sensation in my Occiput, (back of the head, above nape of neck) a sort of discomfort 24/7, as if there's something there that shouldn't be. It is also accompanied by Dizziness/imbalance, falling sensations, falling backwards sensations, flying, rocking head, all originating from the Occiput. This makes walking difficult at times. Sometimes when I'm walking I can feel my body turning to one direction, not the head, just the body, even though it's not. At night when I'm trying to sleep it worsens tenfold and as I'm laying I feel like I'm falling or flying and the pressure sensation almost feels like crushing, I experience several "jerks" also originating from there until after an hour I finally sleep, I can feel strong pulse in the temple regions of my head too before sleeping. Yesterday I was in an elevator for a while and after getting off I could feel vigorous up and down senations at the back of my head for several minutes. There's no pain involved, it is but very rare - as in there comes a day once a month or once in 2-3 weeks that I experience pain in the Occiput. It goes away the next day  after sleeping.

I think this causes anxiety/stress that causes other symptoms I get like heart palpitations, ectopic heartbeats(sometimes feels like a kick in the chest), shortness of breath, nausea at times, body tremors, rare chest pain. Or these might be associated with Acid Reflux/gerd, I have not been diagnosed with it but I think I have it since I experience a lot of burping, burps that bring particles back up my throat, burps that bring burning sensation in the ears, chest burn and constant weird noises from my abdomen at night.

Its been over a year since I'm going through all this, I had a Brain and also Cervical Spine MRI done back in July 2016 and they both came out clear. I had met ENT doctors during early 2016 and they couldn't find anything wrong. I haven't consulted any doctors since July.

Ive had all of this to a T.  I dont have the dizziness to the extreme you do but feel disoriented some.  I am 32 now but at 17 got a tic disorder where id twitch my head or crack my neck constantly to relieve the head pressure.  At 23 i had OCD come out of nowhere very bad and at 28 I dropped to the floor and called an ambulance because i thought i was having a stroke.  I have been told it is anxiety and panic attacks (this all started from one attack I had while fighting a sinus infection).  Would be interested to know if you have any anxiety, panic attacks, ocd or tourettes as well?  I still have all my symptoms but take clonazepam and that has kept me calm during my anxiety attacks.
