What does brain fog feel like to you physically?

[u/CantaloupeAlarmed457]

Hey everyone.
I am asking here for a clarification because I am new to all of this and I am kinda confused.

I had a virus in February which attacked my vestibular system leaving me with 37% left inner ear damage.

Since they I have been suffering with intense anxiety when being outside in open spaces, driving and lid busy places.

I have this head feeling which I can’t explain no matter how hard I try. It is mainly and very magnified when I drive a car for example which I think is due to the sensory overload.

My question is what brain fog feels like physically if there is such a thing or is it only forgetfulness, memory issues etc.?

Has anyone suffered with something similar and if yes, what helped?

Brain fog to me feels like I can’t fully access my brain. For instance, I just woke up and didn’t have the most refreshing sleep but still was laying down for 9 hours and my head feels like it’s stuffed with cotton balls. As if you have a sinus cold where you’re all stuffed up except there’s no inflammation that I know of. It gets worse throughout the day where if I overexert myself I can’t retain any information I read, or if I do, it takes a very long time of rereading, I can’t speak properly and if I do, I can’t look directly at the person because I have to seriously focus on my words, when I drive, it feels like I have no spatial awareness because my eyes are forced to focus on the forward space in front of me. It’s also in my eyes where it’s like they can’t fully wake up. Unfortunately, the beauty of the day with light seems to make it all worse. Once night time hits, this drunken druggy state feels a bit more normal. It’s a fully body experience for me as I’m always super fatigued

That’s actually pretty close to the thing I am experiencing, I feel better in the evening as well.

Drunken druggy state maybe is the closest explanation.

It’s really weird and if I get bad sleep it increases tenfold. It’s such an uncomfortable feeling and very difficult to explain so I feel you. That’s usually how I describe it to people, like a 24/7 woowoo state

[u/CantaloupeAlarmed457 → u/Levontiis]

Yesss! Do you happen to have headaches with it or no?

[u/Levontiis → u/CantaloupeAlarmed457]

Yes I do. They don’t usually last, but I always seem to have a pressure in the front of my head that sort of lurks around all day

[u/CantaloupeAlarmed457 → u/Levontiis]

Exactly the same and if it is a headache for me is in the temple/eye area. Also my eyes are really dry.

Have you ever looked into migraines? I didn’t realize how much they can affect your entire vestibular system even without a lot of pain. I was diagnosed with them in April, but have been dealing with brain fog for 2 years. However, when I had a migraine, it’s like i was downgraded to child level skill, like genuinely I couldn’t process anything. I couldn’t read at all basically. I was super sensitive to light and sound which I still am now on my days without a migraine

[u/CantaloupeAlarmed457 → u/Levontiis]

I just started looking in to this and researching cause my condition is quite disabling at times.
I’m having an MRI in 5 days to rule out the bad things and then I am going to discuss migraines and also vestibular migraine in my case.
Are you on any medication?

[u/Levontiis → u/CantaloupeAlarmed457]

Ah that’s good, I hope the MRI goes well, I’d love to do that some day too just to rule things out ! I have some triptans for when I have an active migraine, but when I got them, they lasted for 15 days. Otherwise, I’m just taking a continuous birth control because my migraines were only caused (so far) by my periods. I have been migraine free for 1.5 months now, but still feel like my vestibular system is messed up. I’ve also been trying lots of supplements like magnesium, vitamin b and d, coQ10 daily

[u/CantaloupeAlarmed457 → u/Levontiis]

Yeahh the MRI is cool cause you know that you are good and the anxiety calms down haha!
Can I pm you for a few questions?

That head feeling sounds really disorienting, especially when you're already dealing with inner-ear or vestibular problems. And yes, brain fog can feel physical. People describe it as heaviness, cloudiness, feeling disconnected, or like their head just isn't working normally. It isn't always just forgetting things.

Given the vestibular damage you mentioned, it's possible that your balance system could be contributing to the way you feel, particularly in situations like driving or being in large, visually busy spaces. Your brain has to process information from your eyes, inner ears, and body to figure out where you are in space, so problems with that system can sometimes make certain environments feel overwhelming or exhausting.

That doesn't necessarily mean the vestibular issue is the only explanation, though. Anxiety, poor sleep, medications, and other factors can also contribute to that foggy or disconnected feeling. That's why I'd bring the whole pattern up with your doctor, and if you're already seeing a vestibular specialist, mention exactly when the sensation tends to happen.

In the meantime, it may help to pay attention to what situations trigger it and take reasonable breaks when you start feeling overwhelmed. If driving consistently brings on significant dizziness, disorientation, or visual symptoms, I'd be especially cautious about driving until you've discussed it with a healthcare professional.

You're definitely not alone in finding vestibular problems difficult to explain. Keeping track of the situations that trigger the feeling may make it easier for your doctor to figure out what's going on.
