Hi Bev and Welcome to KA.
I am not happy to hear that you have AS, but glad that you found us and have learned so much already. It was the same for me and many others here.
It sounds like you received a lot of good info already and I can't add too much to it other than echoing some of the others...stay away from a chiro! No Chiro in his right mind would touch a person with AS or any sort of spondylarthropathy. Physical therapy is your best bet, especially aqua therapy.
My opinion on college and whether or not you should continue...keep on going for as long as you can. We have others here who are in college and they are doing their best to give it all they can and not let this disease stop them. If someday it gets too bad that you can't continue, then look into online classes, like I did. But for now I think quitting is something you'll regret if you do.
Again, welcome to KA and I look forward to more of your post.
Welcome hugs to ya,
Lisa
