I wouldn't say that your Chiari Malformation won't "ever change", it is possible, and mine did. I was at 5mm to 7mm within a year. I get bad neck tremors, mild hand tremors, and migraines very frequently (my neurologist put me on an oral dissolvable medication called Nurtec, and I do 1x monthly injections at home called Emgality). Tylenol doesn't really relieve my pain/migraines either. I found that most of the time, through research and from what doctors say, is that you are likely born with it but symptoms can come on anytime, mine was onset due to physical trauma. I get a lot of the symptoms you have too, minus the feet tingling. It's hard to find a neurologist who cares to really evaluate or help with this since there's not a whole lot of information out there. It took me 5 years and countless doctors to diagnose me finally, after being told "it's all in my head" by my primary physician, who also said "you just need to see a therapist". Turns out it's the Chiari, not my mental state (insert eye roll here). You don't necessarily need surgery until you get to a higher range of mm is what I was told, so definitely be glad it's at 4mm right now. I get botox now from my neurologist, she suggested it because of my muscle spasms in my cerebellum/neck area (tremors I say), and on the side of my face (muscle spasms), and this literally helped so much with the spasms/tremors, and I just had my second round. Seems like it triggers with high stress situations, overworking my mind or body. Doing light activity and cardio at the gym seemed to help, but don't lift an overbearing amount of weight, or high intensity (from what I was told). Hope this helps some.
Hi and welcome to the Chiari forum.
By Basic MRI what exactly do you mean? One of the cervical spine? Brain? If you have scoliosis, did they do thoracic and lumbar MRI's then to review that condition? Anyone ever mention tethered cord?
Most Drs feel this way, which to me indicates they were not fully educated on Chiari during med school. I do not know where you are located, but you may want to research Drs that have done extra interests in Chiari and ALL related conditions and are doing research on them.
Personally , I was told the same as you, had headaches in High school and even before, but they peaked in High school....I was sent to shrinks, and told I didn't have a brain tumor and I wasn't going to die....ALL that without any tests being done....WOW...but I will admit it was before MRI's were used to detect issues like they are now, it was also a very expense test at that time and only used for certain studies.
I had surgery after I researched and found not only did I have Chiari, but a partially retroflexed odontoid , along with Chiari, tethered cord and I had times when my CSF flow was stopped...only a CINE MRI can give that information....
Again, I will tell you to research Drs and find a true Chiari specialist.
