Kelsie Cohen, a 31-year-old bodybuilder from Long Island, New York, encountered unexpected health issues during her workouts. Initially, she believed numbness in her hands and feet was due to low electrolytes. However, her condition worsened, leading to a crucial MRI scan.

Cohen maintained a busy lifestyle as a bodybuilder, personal trainer, and single mother. Her routine was rigorous, focusing on training, meal prep, and caring for her son. Despite feeling fatigued, Cohen attributed her symptoms to her intense training regimen and diet adjustments.

In May 2026, Cohen noticed a decline in her strength and experienced weakness and cramping on her body’s left side. These issues progressed rapidly, with troubling episodes of numbness in her left hand and foot. Initially dismissing them due to her lifestyle, Cohen later realized the severity when these episodes became frequent, affecting her ability to drive and maintain balance.

After advice from urgent care, Cohen visited an emergency room, expecting to address an electrolyte imbalance. However, bloodwork and a CT scan revealed a mass on the right side of her brain, initially suspected to be cancer. Transferred to a larger hospital, Cohen underwent an MRI, revealing numerous brain lesions associated with multiple sclerosis (MS), not cancer.

This diagnosis changed Cohen’s life. Despite feeling devastated that she had an incurable disease, she received treatment that led to noticeable improvements. Though flare-ups still occur, she manages her condition with medication like Kesimpta, a disease-modifying injection to slow MS progression.

Adjusting to her diagnosis, Cohen modified her workouts to accommodate her body’s needs, recognizing the importance of rest. She shifted from relentless training to a more balanced approach, valuing nervous system health.

Cohen uses her social media presence to raise awareness of MS and advocate for listening to one’s body. She wants others to understand the importance of paying attention to health signals, sharing her experience to inspire support and proactive health care.

She expresses gratitude for her progress and hopes her story encourages others to seek medical attention when needed and show that living with MS is manageable.
