Living with multiple sclerosis means struggles and triumphs

(CNN) — It started in May of last year for Beth Ulibarri, as she would go on the occasional long run.

“I would experience a tingling sensation throughout my lower legs. I described it as feeling like something was tickling my legs from the inside and just figured it was my muscles firing away from the exertion of the run.”

Less than a year and many medical tests later, the Albuquerque, New Mexico, resident was diagnosed with multiple sclerosis, or MS.

“My biggest struggle has been dealing with the unknown — questions that do not have answers,” she said. “Concern for my children — will they get this disease as well? Concern for my future. Will I end up in a wheelchair? Concern for how my husband will handle everything to come.”
