Hi. My legs cramp only at night but my poor feet cramp day or night. Not all the time. I too have tried the magnesium,potassium...etc. works o.k. symptoms get better for a while. At night when my legs cramp and twitch I rub on aloe heat lotion - this stuff is wonderful...legs stop hurting within 10 minutes and I can sleep. I haven't tried it on my feet during the day...duh...I guess I remember next time. No doc. has any idea what I'm talking about. I am asthmatic and talk quite a bit of medicine daily. Anyone have comments or suggestions?
