I have just been diagnosed with an arachnoid cyst. I am terrified! I have had headaches, dizziness, numbness and tingling in my left arm and hand, severe fatigue (I could sleep all day), throbbing in my head and more! I had surgery years ago on my left ear for otoschlerosis and was horribly sick for weeks after from dizziness. Took half a year to overcome most of the dizziness. Not wanting to have another surgery especially on my brain. I'm getting more emotional lately and less patient with everything. Yesterday I was hot/cold all day like my internal temp control was out of wack. Had a friend die recently from a brain tumor so my anxiety level is rocketing!
