Background: Multiple sclerosis (MS) presents a wide range of clinical symptoms, historically understood through long-term studies of earlier patient cohorts. However, due to improved diagnostic criteria, modern patients are diagnosed earlier and benefit from effective treatments, altering the disease’s natural history. This study aimed to assess the clinical symptoms of MS patients in a modern population at various stages: before diagnosis, at diagnosis, during the disease course, and at the time of the survey. Methods: This was an observational study with retrospective and cross-sectional components; patients that fulfilled the 2017 revised McDonald criteria for MS completed a survey evaluating demographic and clinical data. Results: We included 163 patients, 69.9% female, with a mean age of 48.21 years; 87.1% had relapsing–remitting MS (RRMS), with a median EDSS of 2.0. Before diagnosis, 74.2% of patients experienced symptoms, mainly sensory issues (39.3%), fatigue (29.4%), and imbalance (27%). Motor and coordination symptoms were more common in progressive forms. At diagnosis, sensory (46.6%) and motor complaints (36.8%) were most prevalent. In RRMS and secondary progressive MS (SPMS), sensory and motor complaints predominated alongside imbalance, while primary progressive MS (PPMS) was characterized by motor, imbalance, and genitourinary symptoms. Throughout the disease, sensory symptoms were most common (76.1%), with fatigue (73%) and motor issues (62.6%) more prevalent in progressive forms. At the time of the survey, 50.7% of RRMS patients were asymptomatic, while progressive patients continued to experience motor symptoms, imbalance, and fatigue. Conclusions: The study reflects the modern spectrum of MS symptoms, consistent with previous research.
