question: Hello..I am wondering if you have any idea why I get these leg problems at night. Only at bedtime do I have these problems. I get a sensation starting in my lower foot (the arch of my foot) and it runs all the way up my leg..it feels like an electrical impulse. It wakes me up at night, I can t sleep. The sensation itself is soo intense it sometimes takes my breath away. I don t understand. Please help.
