Works like magic !
I am 3 weeks post-op for knee replacement surgery.  I have terrible muscle spasms.  Tried everything including Epsom salt foot baths.  Not much help here.  Saw the ad on Amazon for Epsom it and I am so glad I did.  I massaged it into my foot and back of my leg.  Finally was able to sleep with no muscle spasms.
