Comorbidity is common in people with multiple sclerosis (MS), and comorbid conditions contribute substantially to their symptom burden.1,2 Many symptoms are, however, 'invisible' and can have a substantial adverse effect on the quality of life of a person with MS. 3,4
Invisible symptoms are those that we do not see when simply looking at the patient or meeting the patient initially. With many patients, it takes time to speak with them and get to know them before they are comfortable sharing what they consider private or embarrassing symptoms such as sexual dysfunction, bladder symptoms, and so on.
