So this may be a bit long but i will try to make it as short as possible.

i always was an anxious person, health anxiety, OCD ... all that

But all of my health anxiety never felt "real" .. i always thought something might be wrong with me but i never felt any physical symptoms..

Every time i drank too much or smoked weed for the past year i sometimes felt this weird buzzing feeling on my scalp and brain fog/feeling like im about to faint for a few days after.

This changed 4 weeks ago.

Im a college students and had alot of free days so i drank alot, 4 nights in a row.

i stopped the binge and yeah, woke up with a bad hangover.

i ordered some food and when i came to pick the food i started feeling faint and i was shaking, and i had this buzzing feeling in my head. The shaking stopped after i finished the meal but the dizzy feeling and buzzing sensation on my scalp persisted for about 3 days. But on the first day i got deathly scared that something very bad happened to me and that i maybe just had liver failure or had a stroke. So i did some tests ... pulse : normal, blood pressure : normal, Bood sugar : normal.

Then it dissapeared and i felt fine. And then one night i had 3 beers and it all returned...2 days after that i felt the "i believe im going to pass out" again on my ride home on the bus and i had a mini panic attack .. then it dissapeared again after few days.

It dissapeared completely and i even drank beer, even got wasted one night with my friends and no buzzing/dizziness was present. But the anxiety was there...i kept believing im about to pass out.. but i never did pass out.. i believed it must be anxiety because other than the fear of passing out there was no more of the buzzing sensation on my scalp.

Today the buzzing returned, i did not drank yesterday and yet its there again, only difference is that i no longer feel like im about to pass out all the time.. the dizziness is much weaker but the "buzzing" feeling is strong like on day 1 when it started.

I doubt i have any alcohol related damage, i had liver tests done a year ago and my doctor said it was in perfect condition. I drink about 13-15 beers a week. But some weeks when i have no school i drink more.. some weeks i drink none.

Many things trigger the "im about to pass out" feeling like going to a grocery store, standing in a bus, today my vape turned off and i thought it was on and when when i tried to smoke it i expected it to be on and the absence of vapor when i breathed out cause me to feel like something is wrong... when i reached for my pen in school and it was in a different position it caused me to feel that again... its very hard to explain.

But the weird pressure/buzzing feeling on my scalp ? i dont know how to explain that so thats why im asking if anyone here has this ...

In my country the doctors are notoriously bad... they perscribe xanax like candies and my fathers cardio doctor told him to drink 2 beers every day to help with stress and high blood pressure.. so i kind of try to wait if it dissapears on its own.

I also had covid twice so idk if this could be long covid....

this could be so many things... i tried to find diagnosis online and everything points me towards anxiety but you know the feeling... "these symtoms are also similar to this (random terrible disease)"

I told my father about this and he told me that he feels the same thing .. but he has high blood pressure and take meds for blood pressure...and he also has problems with health anxiety.

If this persists i will go to a doctor, but to make sure that this is 100% anxiety i cant even imagine the number of tests that will have to be done... and with the quality of healthcare in my country im afraid i wouldnt get many answers..

I never actually passed out, i also started doing high intensity cardio.. my heart rate reaches 180 pbm during workouts and i never faint... the feeling happens 95% when im calm and not doing any physical stuff...

Also the buzzing/feeling faint dissapears almost completely when im drunk...

i dont know what this is if not anxiety, it "feels" like my brain is not getting enough oxygen but i guess i would not be doing sports after 4 weeks if that was the case... i dont know...

I kind of hope that this is "just" anxiety but at the same time i really dont want to deal with this for the rest of my life...

Also.. i dont have the POTS sydrome, i measured my heart rate while sitting and standing and its okay. 

The only time i felt something like this is the day after i smoke weed, but it never caused me anxiety because to me this was always just a "weed hangover" that dissapeared after a day.

Another thing that may be important is that both instances when i felt the "buzzing" thing was after i had diarrhea.. day 1 was after 4 days of drinking beer... and yesterday i ate bad yogurt and had diarrhea again... But i head diarrhea before and never felt the buzzing scalp stuff...

I stopped smoking weed about a month ago btw... and i was never a regular smoker so i dont think this is weed withrawal or anything.
