I've rarely seen people post pictures of scans and ask for opinions. Personally, I think that could be a little reckless as you never know the qualifications of the person responding. That being said, I personally posted a response on two pictures and I'm still shocked that they were two different people. And there is still yours. I'm sure someone will look, perhaps I will, too. Remember, though, that we are NOT professionals and sometimes these scans are very difficult to read, especially when taking one image alone out of a series. Also, honestly I don't think it's very wise to put your hope in random posters :(
P.s. I do understand your frustration and possibly a little fear. Just remember that if you do have Chiari (or any similar condition), stress and anxiety WILL make symptoms worse. Please take care of yourself and take things one day at a time.
Best wishes,
Annie
Unfortunately, I am not very good at reading an MRI. I am sure that there are people who will respond but may have been busy or out of town. I know how stressful it can be waiting for an answer and sometimes you do not get the answer you expect. I hope you are having a good day otherwise!
