The 31-year-old actress said she became terrified after losing feeling in her hand and suffering a headache and heart palpitations.

She was at home with her husband Cash Warren when she lost feeling in her arm and had to be rushed to hospital.

“I thought I was having a stroke last week. I really, really thought I was,” she said during an interview on Jimmy Fallon Live.

“It was 2.30 in the morning and I woke up and my hand started to go numb. The whole entire thing went numb.

'It was dead, I couldn't move it. My whole arm went numb, I got cold sensations in the back of my neck to the front. I can't move my face.”

After checking her condition on the internet she discovered that they were all symptoms of a stroke.

The mother of two even attempted to phone her children’s paediatrician for some urgent advice.

“I texted my paediatrician. It's my kids' paediatrician, but it's the only person who will answer me at 2.30 in the morning,” she said.

“I texted him and I said, "I have these symptoms... it's all going downhill!" He was like, "You're a little young for this...'''

She was eventually taken to hospital where she underwent an MRI scan. Luckily, the test revealed she was suffering from carpal tunnel syndrome, a relatively common condition which causes pain, numbness and a tingling sensation in the hand and fingers.

The drama is all part of a busy year for Jessica, who is currently filming Sin City: A Dame to Kill For, reprising her role as stripper Nancy Callahan in the follow-up to the hit 2005 action crime thriller.

She also has three movies coming out this year, is being considered for another role, is busy promoting her new book, The Honest Life, and being mum to her two young children, five-year-old Honor and two-year-old Haven.
