What MS can involve
Multiple sclerosis affects the nerves in the brain and spinal cord, and few conditions vary as much day to day. Fatigue is the symptom people with MS most often name as the hardest, and it is also the one least visible from outside. Heat makes many symptoms louder, which is why a warm room can undo an afternoon.
Numbness, weakness, balance, vision and bladder symptoms can come and go, and the gap between appointments is long. A record kept as it happened shows what changed and when, rather than leaving you to summarise months of variation in a short conversation with your MS nurse or neurologist.
