Bodybuilder Discovers Multiple Sclerosis After Numbness Episodes

Kelsie Cohen, a 31-year-old bodybuilder and personal trainer from Long Island, New York, initially thought her numb hands and feet during workouts were due to low electrolytes. However, her persisting symptoms led to a shocking discovery through an MRI scan.

Cohen has an active lifestyle, balancing her roles as a single mom to a toddler and a personal trainer. She maintained a strict routine, focused on training clients, personal workouts, and meal preparation, while ensuring her son’s well-being.

Symptoms started in early May 2026 with a noticeable decrease in workout strength. Cohen attributed this to reduced calories and increased cardio, part of her bodybuilding regimen. She soon experienced weakness and cramping on her left side. The symptoms, including numbness in her left hand and foot, intensified and led her to the hospital within a week.

Initially, Cohen believed these episodes indicated an electrolyte imbalance. But when the symptoms became frequent, affecting her safety while driving and causing loss of sensation upon standing, she sought medical help. Urgent care suggested it could be serious, prompting a visit to the emergency room.

At the hospital, bloodwork and a CT scan were performed. The bloodwork was normal, but the CT scan revealed a mass on the right side of her brain, initially suspected to be cancer. Further assessment at a larger hospital included an MRI scan, revealing numerous brain lesions indicative of a demyelinating disease. A subsequent spinal MRI confirmed multiple sclerosis (MS) in late May.

Cohen was devastated by the diagnosis of MS, a chronic, incurable disease. She faced significant challenges, including dizziness and leg spasms, but medication brought noticeable improvement. Cohen manages her MS with Kesimpta, a disease-modifying injection, and by adjusting her workouts.

She now takes a more cautious approach to training, balancing activity with necessary rest. Cohen uses her social media platform not only to share fitness content but also to raise awareness for MS. She hopes to inspire others with MS and emphasize the importance of listening to one’s body.

Cohen stated, “Listening to your body isn’t weakness. I used to think pushing through everything made me stronger. If your body signals something isn’t right, don’t ignore it.” Grateful for her progress, Cohen aspires to help others recognize the importance of seeking medical attention when needed and understand that life after an MS diagnosis continues.
