I am very sorry to hear your daughter has MS. All of us who have been touched by it, ourselves or a loved one, hate it...   I personally have not heard of all these stages, but if she truly has relapsing remitting, then she is not at an "end stage". The MS has to go from relapsing-remitting to Primary Progressive before "end stage" (of life) is even discussed...she may need therapy for help with swallowing problems or thickeners added to foods and fluids so that they don't get accidentally aspirated into lungs...   While swallowing problesm could could go away during remission, it's a new thing for her, so she should go back to her MS doctor. Swallowing problems can lead to aspirating foods and liquids which can cause pneumonia which can be life threatening...Don't ignore it...let the Docs know...take it from there...
