Bodybuilder’s Journey: From Numbness to Multiple Sclerosis Diagnosis

Kelsie Cohen, 31, a bodybuilder and personal trainer from Long Island, New York, experienced a significant shift in her health journey. Initially, she thought the numbness in her hands and feet during workouts was due to low electrolytes. However, as her condition worsened, further investigation revealed a different story.

A Rigorous Routine

Cohen maintained a busy lifestyle, juggling her role as a single mom, a bodybuilder, and a personal trainer. Her day revolved around training clients, her workouts, and caring for her son. She noted that her regimented lifestyle may have contributed to more stress on her body than she realized.

In early May 2026, Cohen noticed a loss of strength during workouts. She attributed this to her bodybuilding preparation, involving lower calories and increased cardio. Soon after, weakness and cramping began in her left side, along with numbness in her hand and foot. She initially dismissed these symptoms, suspecting an electrolyte imbalance.

Escalating Symptoms

The numbness episodes soon became frequent and severe. They occurred multiple times a day, affecting her ability to drive and causing her to lose sensation on her left side. Urgent care advised her to visit the emergency room for further evaluation.

Initially suspecting it was an electrolyte issue, Cohen was reassured by normal bloodwork. However, a CT scan revealed a mass on her brain, initially thought to be cancer. Further assessments at a larger hospital suggested otherwise.

Diagnosis of Multiple Sclerosis

An MRI scan shifted the diagnosis from cancer to a demyelinating disease, leading to a diagnosis of multiple sclerosis (MS) after further tests. Despite the doctors’ relief that it wasn’t cancer, Cohen felt devastated by the incurable nature of MS and the limitations it posed.

Her time in the hospital saw rapid deterioration, including dizziness and leg spasms. Medication was administered, providing noticeable relief. Cohen learned to manage her MS flare-ups and began treatment with Kesimpta, a disease-modifying injection.

Adjusting to a New Normal

Though Cohen can still work out, she has adjusted her routine to meet her body’s needs. Emphasizing a nervous system-friendly approach, she now incorporates more rest and less intense training sessions.

Cohen expressed that her new routine has taught her the importance of listening to her body. She works to raise awareness for MS on social media, sharing her journey to inspire others to seek medical advice when needed.

“Listening to your body isn’t a weakness,” she stated. She encourages others to trust themselves and seek medical attention if something feels off. Her hope is to help others feel less alone and to show that an MS diagnosis doesn’t mean the end of an active life.
