Christina Applegate has found herself "screaming" in pain amid her struggles with multiple sclerosis

The Hollywood star said on the 'MeSsy' podcast: "I lay in bed screaming - like, the sharp pains, the ache, that squeezing."

Christina admitted that she now struggles to perform everyday tasks, including answering her phone and using her TV remote.

The actress shared: "I can't even pick up my phone sometimes because now it's travelled into my hands, so I'll, like, try to go get my phone or get my remote to turn on the TV or sometimes, I can't even hold them. I can't open bottles now."

Christina also struggles to get out of bed in the morning, explaining that her bedroom floor feels like "lava".

She said: "I put my feet on the ground and they're hurting, like, extraordinarily bad to the touch. I was like, yep. Gonna get back in my bed and pee in my diaper because I don't feel like walking all the way to the damn bathroom.

"I actually don't lay here and pee in my bed diaper. That's just a joke. But it's like it's so freaking painful and so hard and so awkward."

Christina previously revealed that she's made her friends fully aware of her physical limitations.

She said on the 'MeSsy' podcast: "I always say, sure, if you want to go to lunch, just know - and you have to know this and you can't be mad at me - that if right before you come to pick me up, if I say can't do it, you can't be mad. It's my little disclaimer."
