Could An Unattended Tailbone Injury Cause MS In Future?

Could tailbone injury due to falling on a boat (wooden slippery surface) which is not treated in time produce or cause MS later? Any relation between these two and vit b12 deficiency? Concerns my mum who has ms for about 30 years, can still walk with difficulty at home and has position of tummy slightly disoriented towards left side and much larger in size. The fell was a few years before the diagnoses of ms.Has often formation of muscle nodules aroun knee area and upper, painful when pressed. Will be grateful to hear comments ... and what might help. She has from time to time massage, reflexology....takes evening primrose oil, etc...Many thanks in advance. S She is 79 Has had acupucture 10 years ago.Cooks at our restaurant, we provide every help. Left hand limeted use. Left leg and foot much weeker and thinner.Some doctors in England doubted that she has ms but tests showed presence.
