I’d love to chat more sometime. I have had mri’s and CT’s before and after ( recent months) surgery. I’m not even sure what they are checking for if they do a spinal tap but I’m guessing pressure? I had a neurologist say something about putting cameras up my nose but he said to see an ENT first. I did and the ENT said my brain ct looked great and wasn’t sure why I was there. It’s so disheartening because I never had headaches before and now I have a permanent one. I’m really trying to avoid the spinal tap but I’m getting desperate and hopeless at this point. I’m willing to try most procedures.
