Brain bouncing in skull

[Ball123]

When I run or jump or otherwise move my head it feels like my brain is moving around inside my skull. It feels like it is somehow loose in there. It feels a little bit like I get a punch everytime I jump and my brain crashes into the skull bone. It also hurts if I shake my head or if I go with the car over a bump in the road. Maybe it is my blood moving around in my head that I feel. I have had this for a long time but I still remember how it felt like to be healthy. I wish to come in contact with other people who suffer from the same thing as I do. Maybe we can solve the mystery together.
All ideas and comments are welcomed.
Have a nice day!

My prime hypothesis is that I am suffering from a mild case of intracranial hypotension, which in turn causes the blood vessels to dilate through the vaccum powers of the Kellie -Monroe doctrine, and that this in turn causes my sensations. But I am not at all sure. I have googled a lot and it seems like there are a number of people suffering from exactly the same thing as I do. But a lot of them has taken MRI scans that came back normal. So, is it really possible to miss intracranial hypotension on a MRI scan? Maybe it is, especially if it is a "mild" case, and you take the MRI without contrast liquid? And since you take the MRI lying down the displacement of the brain is not so easily spotted (if it at all exists in a mild case). But as i have read, people suffering from intracranial hypotension usually have trouble with g-forces (many of them can not even sit up, that is they can not even take one g). I can take one g since I can stand up, but I can not take much more than that, like jumping and running and so on. I also suspected sinus problems, since I had a constantly plugged nose since ten years ago (only one nostril). But the sensation is mostly from the back of the head or the middle. And also I treated my nose with cortisone spray for two weeks without improvement in neither the nose nor the "bouncing brain". I also suspected low thyroid function but I tested for that and it came back negative. Other symptoms that I have are bradycardia and that I sleep too much. I have had neurological symptoms but only occasionally. Lately I have experienced lightflashes when I close my eyes and also some nystagmus and my hands are rather shaky, but I am not sure that that is something strange really. It is all a mystery to me:)..

I am not quite sure how to explain that feeling of your brain moving around inside your skull. Often, if we play close attention to our bodies, we will notice things that we don’t always have a good explanation for. The most important thing is to make sure it is not something dangerous.

In your case, I would want to make sure you are not having any neurologic symptoms, such as weakness or numbness in your arms or legs, dizziness, or vision changes? I would also want to know if the symptoms you describe getting worse over time, or seem to be stable?

It’s hard to say without knowing more of your history and being able to examine you. I would recommend talking with your doctor about your symptoms. One possible explanation is that it could be related to your sinuses and eustacian tube dysfunction, and it’s possible that allergy medication may help you. If there is anything neurologic concerning to your doctor, he/she may want to order an imaging study of your brain, such as an MRI.
