For 5 years now, I have been living a nightmare. It started after a strong weekend of drinking, but about a year before that after drinking, I collapsed the next day when my body started tingling all over. Forget about the drinking, that's not my problem, that's just a background of when this started. I no longer drink more than a couple of drinks every week. However, I have a major problem, since that time my head often gets feelings of significant pressure in it .When I lie down, sometimes I get a little dizzy. Often when I lie down, especially in the mornings, I can sense some fluid moving in my head. It is in the back part of my head just slightly higher than halfway up. It's happening inside my head. It is not imagined. I can feel and hear it as if it were lots of little bubbles moving or as if some fluid has broken past some tight barrier and is squeezing out. I also have a continuous need to move my neck around a lot because when the symptoms are bad, my neck cracks a lot esp. near my skull. My neck muscles sometimes get tightened up too. You won't believe it, but when I'm having a lot of pressure, my fissures in my skull will also pop and crack. I have undergone 2 MRIs where they checked veins and arteries and everything was normal. I have had my CSF checked with a Lumbar test and it did not register pressure. I would swear that CSF is getting trapped in my brain somewhere, but it's just not showing up. I am often tired, etc. Here's another weird part though. When this started, I had a swelling around the lining of my lungs as well. That had build up a little fluid in my lungs too. Prednizone was prescribed by my doctor and it healed. However, I get generalized swelling in my lung area from time to time. I would swear that it only happens around flat bones. Anyway, i want to relieve the pressure in my head. Something is definitely wrong when you have fluid releasing in your brain due to pressure. But, what can I do if the MRIs came back negative? Please help me. My quality of life is not improving and it's very difficult.
