I am new and have the same poster fossa cyst 5.6 cm. I just found this and wanted to reply. My cysts shifts causing Spinal fluied blockage, When I am walking or cleaning, my symptoms for this is:
Head pressure, dizziness, a feeling of fluid behind my ears while not being able to speak clearly, I become naselly when this happen. its almost like you are talking with your ears under water. spinal pain and lower back pain which is caused by not enough fluid flowing all the way down your spine. after the episode is over you are left with sharp pains in your head because the fluid that built up has gone down and you head has to reajust.
does this sound like you?
