Near whole Right side of body numbness, stiffness and weakness

Any advice on calmming down the body? Have Relapsing Remitting MS. Ms nurse says go to A&E if it gets worse and talk in a few weeks. No other advice other than anti depressants because its stress related. What has worked for you? Over a week the numbness grew from just the fingers to most of R side. I've done Wim Hof breathing exercise before, which ill start again plus hand, knee stretches / overall body stretches. Walks that im not sure have helped? Thanks!
