Hi - I used to get calf and feet spasms at night when I was working - I think it was beause of the shoes I had worn during the day - I'd go from heels all day long to flats to go play on the beach..... get them rarely now caues I'm usuallly barefoot inside - but do get them occasionally - if I've put some kind of stress on my legs during that day....

Anything different on your feet or??? lots of stair climbing or something along those lines?
