Question: I've recently had a craniotomy, radiation and chemo. When I stand up from sitting 30 minutes or more, I feel great pressure in my head, dizziness, and tingling hands. Doctors have no explanation. Why does this happen?

Brief Answer:
Two possible explanations.

Detailed Answer:
Hello and thanks for using HCM.

I have read your question and understand your concerns.

Yours, certainly, is a difficult condition to be explained.

Two possible explanations come in my mind when reading your query:

1. Iatrogenic episodic ( or by treatment induced ) Chiari malformation, a condition where cerebellar ( small brain ) tonsils by gravity, close temporarily communication of cerebrospinal fluid between spinal cord and brain, resulting in temporary increase of intracranial pressure.

2. Low intracranial pressure that inverted after changing positions.

The second possibility could be assessed by small brain ventricles found in MRI imaging study.

Hope you found the answer helpful.

Take care.

hi my name is Denise and 3 years ago I had a Chiari Malformation decompression. 6 weeks later I had to go back in for another operation because alot of fluid was building up and I had a big bulge on the back of my head. I have been suffering with balance problems dizziness and fainting spells ever since. I recently discovered that the left side of my medulla is being pressed by an artery and also that the cerebellar tonsils are falling below the crainiotomy. I need you help in understanding what all this means.

I think that I may have had seizures in my sleep. Most recently, I awoke to my entire body jerking like someone was repeatedly shocking me. I was fully aware, but could not do anything about it. This has happened a couple times before in the past few years. It lasts about a few seconds up to a minute and then when it is over, I usually roll over and fall back asleep because I am so exhausted. I was recently diagnosed with a very mild chiari malformation with some symptoms of dizziness and body weakness. I am extremely healthy otherwise.

My skin turns bright red in splotches like a sunburn . I feel like I am burning from the inside out. I have systemic swelling. This has been going on since my last cervical fusion in March. I have extreme fatigue , loss of appetite , nausea when eating, blurred vision and dizziness . I have pain on my left side under the rib cage with any pressure. I was diagnosed with mono. However I had this when I was in college and I am now 47, so I am not sure if this DX is correct. The cervical fusions in Dec 2011 and March 2012 were due to a motor vehicle accident where I was rear ended and shoved into the cars in front of me. It was a 4 car pile up. I had had contant nausea and vomiting since 11/10/11 (the day of the accident) which disappeared after the March surgery. I have a connective tissue disorder called Ehlers Danlos Syndrome and Chiari Malformation I. I had tethered cord syndrome for which I already had surgery. I also had 2 posterior fossa decompression for the Chiari. With the last decompression, I had a metal plate inserted in the back of my head and rods fused to C2 and C3. I also had a decompression done at L4/5 as the tethered cord surgery caused complications. I was doing great and finally getting back to work before the accident.

I am 62 years old and have chiari malformation 1. I had a brain stem stroke 20 years ago with right side weakness that has not gone away. Lopressor has been prescribed for fast palpitations while at rest. I can't balance myself with the weakness and this drug. It doesn't stop the heart from fluttering. Maybe the Chiari and brain tonsils finally caused problems with my heart that drugs can't correct. Would that be possible?
