Do you feel the neck pressure or headache when you stand up or sit up? What are you eye issues? I have just been diagnosed with Intracranial Hypotension and I had a massive headache one day and then the next day, I had huge neck pain and pressure and it was really bad when I was sitting up or standing. What this condition is, is there was a tear in the lining around the brain and the cerebral spinal fluid is leaking out causing the brain to "sag" or drop, putting pressure on the nerves. I ended up with double vision as the brain is pushing on the nerve that affects the eyes. If you have these headaches/neck pain-stiffness in neck and it is more pronounced when you are standing or sitting up, go to your doctor with this information. This condition is rare and often misdiagnosed.
I've been having very similar symptoms for months now and no diagnosis yet In fact I have the neck/back of the head pressure right now. I actually get this creepy crawly sensation as well. I even ended up in the ER due to a panic attack caused by all of this and I have NEVER had one before.
I'm not on Xanax or any type of meds. Have never needed anything like that for anything
I've had Head and Neck MRI's, two different types of Nerve Conduction studies and multiple blood tests. Nothing...
