Hi, Whitney. Nice to meet you. Welcome to the forum
I'm not a doctor, but it definitely sounds like your symptoms are AN symptoms. Obviously the MRI will tell you for sure.
If it is, it's normal to be scared - I was - but please know that we are here for you. Heck, we're here for you even if you don't have an AN
Seriously, an AN is something you can get through. 99.9% of them are benign - which IMO is excellent news. Depending on the size and location of the AN, you typically have the choice of surgery or radiation - or you may even be able to watch and wait for a while before deciding on a course of treatment.
If you MRI does show an AN, please contact the ANA and ask them for their informational literature. It's written in very basic, easy to understand, terms (not medical speak) and it's an excellent resource. I highly recommend it. They will also send you a WTT (willing to talk) list that has contact information for patients all over the US. There may be someone near you who can tell you where they had their treatment.
In addition, as I said previously, we are here for you. Please don't hesitate to ask us anything, tell us when you have concerns, are scared, or just want to vent. We've all been there and aren't shy about giving advice, opinions, or just recapping our personal experiences.
And you are correct - there IS a light at the end of the AN tunnel.
Good luck,
Jan
