You need to get all your doctors on board with the MS investigation. People with MS do have other health problems especially as we age. People with MS have surgeries and other medical procedures. Get all your doctors on the same page and you should do just fine. I can't see why steroid injections would cause you to flare. MS uses steroids all the time so it is not counter-indicated. The only way it would cause you to flare is if your pain is not managed or if you are very stressed about
this. Again, get all your doctors on the same page - that part is crucial.
