Anyone out there having severe muscle cramps?

I'm not talking about like an ache or soreness. I'm talking about the kind where your whole foot, leg, arm, wrist completely locks up in some mangled looking way and you can do nothing but scream and try and make it straighten out until it stops. It happens at least once a day, but more often than not it happens 3 times and no specific body part. I have even had my hips start doing it. My calves and forearms feel like they have bruises all over them 😣 Does anyone have an idea what might help? (Yes I already eat like 2 bananas a day right now becuz of heartburn that has me choking on vomit in my sleep.)
