I was diagnosed with Chiari Malformation on August 19th, I had decompression surgery on sept the 4th. Recovery is going well. I have had a few headaches since the surgery and omg yesterday's was very bad! Since surgery, the back of my head is numb from ear to ear, and from the bottom to the top of my head!?!? The numbness on the back of my head feels like it spreads to the top of my head one day and then is just on the back of my head the next. Also my left thigh from hip to knee goes in and out of numbness now instantly?!?! My neurosurgeon told me it's just from the surgery and should go away after time. Has any one had or heard of this? How long did it last or does it even go away? I am new to the chiari world, and googled the mess out of chiari but have not come across the numbness issue. Any feed back would greatly help cause the only answer I receive is "it's all from the surgery". I know it is from the surgery but that's all they can tell me! Thanks!
