Yes,at Times and in past about 2 yrs I've had more BIG jolts/ jerks of parts of body

Yes, especially in my arms and legs too.

Yes I do I was watching my calf before twitching like mad make sure your not dehydrated 😁

Definitely, and according to my neurologist it is part of fibro. I take magnesium and use the old folk remedy of a bar of soap in the bedsheets. I used to take a med that stopped the twitching but it bothered my stomach after awhile. Don’t recall name of it but you should ask your dr.

Do you take magnesium to help with your muscle pain and twitching? If not, give Magnesium Malate a try?

Light stretching and foam rolling will also keep your muscles/fascia loose and hydrated.
