Hi all, I'm writing in here on behalf of my mum who had a knee replacement on Saturday. She had an epidural and sat night & all day Sunday she was fine but Sunday was terrible- she had terrible spasms in her legs and hardly had any sleep. She is home from hospital now but is very tearful and so over tired. She's suffered restless legs for years and can manage on little sleep but obv the spasms now hurt her more. I feel totally helpless and the hospital weren't much use. I really just want to know if this normal? Has the op just flared it up badly and it will settle? It's horrible not being able to do much to help. Thanks.
