(1) Background: The global expansion of teleworking has increased concern regarding musculoskeletal pain associated with home-based working conditions. This study quantified the prevalence of musculoskeletal pain among Brazilian teleworkers and explored ergonomic and environmental factors associated with the distribution of physical symptoms and the multisite pain burden. (2) Methods: A cross-sectional survey was conducted between June and August 2024, analyzing 184 valid responses from teleworkers across various professional sectors. Data were collected via an online questionnaire assessing sociodemographic characteristics, workstation ergonomics, and musculoskeletal symptoms using the Nordic Musculoskeletal Questionnaire (NMQ). Statistical analyses included Pearson’s chi-square tests, logistic regression, and exploratory Random Forest modeling to prioritize predictors. (3) Results: Musculoskeletal pain was reported by 74% of participants, with the lower back (40.8%), neck (36.4%), and upper back (30.4%) being the most frequently affected anatomical regions. The primary ergonomic and environmental factors associated with pain reports included discomfort with the desk and mouse, suboptimal thermal comfort, and prolonged sitting. Odds ratios demonstrated strong statistical co-occurrence between recent and 12-month pain reports, particularly for the shoulders, reflecting overlapping recall indicators rather than temporal symptom progression. (4) Conclusions: Musculoskeletal pain is highly prevalent among Brazilian teleworkers, showing clear links to localized workstation inadequacies and overlapping short- and long-term symptom reporting. These findings highlight the need for targeted institutional occupational health policies, such as ergonomics training and adjustable furniture provision, while future longitudinal research remains essential to confirm causal pathways.
