Keeping a diary specifically to monitor your MS can be helpful to you and your MS team. You could record how your MS alters in response to different factors - such as activity levels, stress or diet - or at different times.
This information will allow you to understand what affects your MS, and can help you to identify trigger factors and patterns. For example, you might find that your fatigue is more severe on a hot day or after a particular activity. Becoming aware of this allows you to plan your work or activities effectively or change how you do things so you can manage your MS better.
A symptom diary can also help you remember what's happened since your last appointment, and keep a record that you can show to your neurologist or MS nurse when you next see them. You could dedicate a notebook or diary to tracking your MS symptoms, perhaps a 'week-to-view' format so you have enough space for notes. Keep this with all your correspondence from your MS team, or print out a ready-made form and fill it in each week. Some free printable symptom diary examples can be found online. Although they may not be specific for MS, they offer a useful starting point.
There are several different mobile apps which are designed for people with MS. Many of them incorporate a symptom diary and may also include reminders for taking medication, recording injection sites, and logging the contact details for your MS team. Some can be synchronised with your Fitbit or the weather to help with plotting trends in your MS.
