So far we have learned that if you have new symptoms lasting more than a day or two, you may be having a relapse. But when existing symptoms worsen, how do you know whether you are having a relapse? I recommend keeping a journal and defining what constitutes a good day and a bad day for you. This way, when something out of the ordinary occurs, you can compare it to what you know to be normal for you. For example, you may know that even on a good day, your feet tingle after you exercise. Then, after a long day, you find your feet are tingling more than usual and you are fatigued. Considering this is an existing symptom, worsened after an unusually long day, it’s safe to assume it’s not a relapse. However, if this bad day lasts longer than 24 to 48 hours, it’s time to call your healthcare provider. However, if you have slowly progressive vision loss during the course of a day, and you have never lost your vision before, this is out of the ordinary. In this case, you would want to call your healthcare provider ASAP. If you are ever unsure whether you are having a relapse, it is always best to call and discuss them with your healthcare provider. Whether it’s a relapse, a pseudorelapse, or something else, they can guide you in how to best manage what you are experiencing.
