One of the most common symptoms for a patient with an arachnoid cyst, is pressure in the head. At first you may not be sure anything is wrong. You may feel a little strange in the head, and it may fade in and out - or come and go. But as your cyst grows, it can start to put pressure on the brain and on in the inside of the skull.
If your cyst is growing, you may start to notice odd symptoms that you are not quite sure if the symptoms are real, or imaginary. They may be subtle at first and increasingly grow over time. Because the symptoms can emerge slowly and subtly, you may even wonder if they are real, or all in your head.
Some of the most common signs of presure on the brain are:
(1) Dizziness - Pressure on the brain can make you feel dizzy - whether it is a spinning dizzy, or off-balance dizzy. It may be subtle at first, but the dizziness can grow and get increasingly more bothersome. You may even experience nausea with the dizziness.
(2) Pressure - The pressure that arises in your head due to a cyst can feel similar to the pressure you may feel when a plane ascends into the sky. It feels like there is not enough room in your skull for everything in there - as if your brain is growing and pressing on the inside of your skull. It can also feel like a lot of fluid in your head, as if you were filling a waterballoon and the fluid gets to be too much in the balloon, so that the insides of the balloon are bulging and ready to burst.
(3) Tight - Too much pressure can make the inside of your head feel full; crowded. It can feel like your brain is being squished. You have an unrecognizable fullness in your head and you want to constantly shake your head to relieve the fullness and help to regain cognitive thinking. You can't think straight. You lose your ability to focus and concentrate.
(4) Vision Disturbances - Your vision may become distorted. Gradually it may seem as if you are looking at the world through distorted glasses. The world may seem more cartoon-like, like images are not real. You may have blurry vision or tunnel vision.
If you are having any of these symptoms, you need to be checked. If you already know that you have a cyst and develop these symptoms, keep record of them and rate them on a daily basis with 1 being not so bad and 10 at it's worst.
Only do what you can do, physically. Do not push yourself too hard or put yourself in dangerous situations, like driving long distances if you know that you are having problems with dizziness, or cognitive skills.
Talk to your doctor about all your symptoms, the severity of them, and if new ones develop.
