Feel free to vent anytime here, it really does help! When the doctors can't figure out what's wrong right away, it's perfectly normal to feel that "its all in my head". Please don't get discouraged, try to think positively and keep pressing forward for answers.
The rubella vaccine can cause a lot of the problems you are experiencing, particularly the joint pain and even the ON. Swelling and pain in the joints are typically not associated with MS. The other things you have mentioned can be tho, but also can have other causes as well.
From what you said, the first MRI was done about six months ago? I hope I'm reading that right. With the new stuff going on, its very important to go back and make the doctor aware. You might consider keeping a journal and write down your symptoms, when they occur, how long they last to see if there is a pattern.
If you haven't seen a neurologist yet, it might be a good idea. You didn't mention any other testing besides the MRI. Have you had any bloodwork to rule out other possiblities yet? Hope you feel better soon, please let us know.
