I tried it. I was having an attack of cramping hands and tried just mustered. Cramps went away. Sent wife to get spicy mustard at store. Thanks.

I drink dill pickle juice with a couple of saltine crackers and it helps my muscle cramps. Hope it works for you.

For my muscle cramps I take a big spoonful of spicy mustard . Seems to work for me. Good luck

Before I Knew I had MG I had muscle cramps at night - a friend recommended pickle juice worked wonders. I don’t seem to have those cramps anymore.

Hi Jay
My understanding over the years people with myasthenia gravis should never take muscle relaxers.
Always double check with your neurologist.
I had severe muscle cramping in my legs at night and I figured out that I needed to keep my magnesium levels low and then they went away. I tried for a couple of years. I had them so severe . I had all kinds of tests. Doctors couldn't tell me what the problem was.
That's when I got on here and I was looking for answers.
Johanna said her neurologist told her to keep her magnesium levels low.
So I decided to check that out and she was absolutely right.
Check your magnesium levels and see where they are.
I keep mine at 1.6 1.7 barely on the line of being normal
It's worth checking out.
I hope that you can find some answers.
I hope this helps. Good luck. God bless you.
