Muscle cramps

  1. Jan 11, 2004 #1
    My right buttocks cramped up today. That has *never* happened before. It was quite unexpected... I was sitting down, and when I stood up, the cramp really hit me.

    Im confused.

    Why on earth would that happen?

    Lack of Mg? Try eating extra banana's they are a good source of Mg.

    Lack of Mg??? How about lake of K?

    well, before that happened i walked around for about two miles with a heavy backpack in warm weather... which is not really strenuous for me.- not enough for muscle cramps at least!

    i have been very sleep deprived all week... maybe thats it?


    anyway. thanks for replying!

    was just reminded that i should take a vitamin. :)

    Don't just take vitamins, take minerals too. As nautica said, it is both K+ and Mg2+ that you'd probably need to eat up on. Where do you get K from? Green veggies?? Noo, that's vit K.. maybe K too..

    Did you do a 'cool down' (for the muscles) after the walk? (removes the lactic acids, fuel of the muscles, before they congeal/harden, which causes {one source} cramping)

    Bacteria production with in the body (I believe, but dont quote me, I will have to look).

    But an external source would be bannanas, as you have already mentioned.

    are you positive it was a muscle cramp?

    i had a herniated and ruptured disk on my sciatic vertabrae... and it felt like a constant cramp in my buttocks... do u have a history of back problems?

    just sumthin to consider and take care of ASAP if thats the case...i'll tell u from experience...sciatica is no picnic.

    other than that i think the lactic acids that parson said sounds about right to me

    I don't mean to be rude, in being forward, but viewed from another (postive?) perspective, it's a "nice" way of your body reminding you that you need regular excersize, regularly, as in it could have been worse, what a lack of good regular excersize does for any, and all, of us...

    Funny, learned that watching Jane Fonda, on Television, when she was promoting fitness...

    Has anyone around you been particularly annoying lately? Could be psycosomatic.

    Heh heh, i'll remember to take supplements when i expect to have annoying company. Or perhaps I could give the annoyers suppositories and balance the equation that way?

    Psychosomatic aside... Did you drink more coffee that day... caffeine kicks a bunch of stuff out of your body, including B vits. But sleep deprivation per se is a form of stress, which increases the body req. of B6, needed for adequate Mg metabolism. Also overall dietary Ca:Mg must be adequate (I believe 2:1) - they compete for absorption and excess of one will deplete the other. (so, say, if you ate bunches of tums for a couple of days, you could lower your Mg levels.)

    Anectodally, when I started exercising I initially observed a distinct inverse correlation between premature cramps and having taken my Mg&K supplements for a few days prior.

    add my vote for the bananas too. and easy on the caffeine.

    That is not neccessarily the case, many many atheletes have problems with cramping.

    Good point, example of one end of a scale, and the example of the other end....all as one, not bad!
