Two weeks after revealing that she is battling multiple sclerosis, Jamie-Lynn Sigler opened up about how the debilitating condition affects her daily life.

“My symptoms are weakness in my right side,” Sigler, 34, told Access Hollywood on Thursday, February 4. “I can’t run. It’s so hard for me. I’m not trying to sensationalize this at all, but the very last time I can remember running was the final scene of The Sopranos. That’s literally the last time I can ever remember feeling that freedom in my body.”

During the series finale of The Sopranos, which aired June 10, 2007, Sigler’s character, Meadow Soprano, ran across the street to a restaurant to join her family for dinner.

The Entourage actress was diagnosed with MS at 20 while filming season 4 of the HBO drama. On January 27, she told the Today show that she kept her diagnosis a secret for nearly 15 years in fear that it would affect her career.

The proud mom of 2-year-old Beau, with husband and pro baseball player Cutter Dykstra, also explained on Thursday how her condition has changed life with her son.

“It’s a lot. It’s a lot for any mom,” Sigler told Access Hollywood. “I do my best [and] I manage. If I know I’m going to take him to the park, I usually take him to a park that’s enclosed so that I just don’t have to worry about him running off. I do everything that any other mom does.”

She added, “I anticipate and think about all the time what and how I will tell him one day. I think when the time comes and when he needs to know, I’m not gonna use the word ‘sick’ because I think that instills fear in a child. I don’t feel sick all the time and I don’t want him to think that way.”
