Hi Chica. Thats a catch 22 question because the answer is that attacks can go either way. I dont know anything about bursitis- but I do know how sometimes symtoms can go into remission for long periods of time and then attack again. The problem is, sometimes when they attack again, they come back worse....and sometimes do not resolve themselves entirely. Im having that problem with my tingliness and numbness of my left hand. For weeks, I just live with it, and its not terribly bothersome, then one day -usually out of the clear blue- it hurts all over again, keeping me awake at night, and causing me to drop things, become frustrated and really in pain. I feel for you.
Of course, the other side of it is that it could be the bursitis, aggravating what is already there, but hasnt been real active...
You should call your doctor. Ask to have him call you back, or speak to his nurse. Tell them exactly what you told us and let them decide if they want to see you sooner....its not life threatening, you know that- but they might want to evaluate you while the symtoms are present....then again, if it is MS related, we all know there isnt much they can do (besides a round of steroids if you really want to go that route) and they might tell you to wait it out. End of March isnt that far away.
I hope you feel better soon. Try NOT to focus on it. You know that will only make you feel worse and make it more obvious in your own mind. I know its real, but you know that with MS anything can happen at any time....this is not horrible, thank goodness- and its not likely to get worse- but try to just let it do its thing...but call the doctor, since its your first 'flare up" they might want to see you.
As for the MRi, dont sweat it. Even if you arent "glowing' at the time they do it, the scar tissue will be there if it is a flareup....either way, you want to get that done to make sure your meds are doing what they are supposed to be doing.
Hugs,
Nikki
