Jenna - Sorry this is causing you so much anxiety. Keep reminding yourself that whatever it is, you are going to be ok. Think positive. I know it's hard when you have all sorts of crazy stuff going on and thinking positive seems like a battle. Also, we are all here to help you through what ever the results may be.
As for the MRI, Ann is correct. We would not, even if qualified, be able to read the MRI. If you are concerned about it, you can always call the drs. office and discuss it with him/her or the nurse/med. assistant.
As for the herniated disc, I know several people that resolved theirs by doing physical therapy as opposed to surgery. But, should you have a herniated disc, follow the advice of your physician(s) (you may want to get 2nd opinions if they suggest surgery as your only option).
Good luck and let us know how things are going for you.
