I appreciate you responding so quickly. I think my problem is different from your Mother's.
My stomach is fine. It's the abdominal muscles that spasm and go into contraction.

My mother had her stomach completely removed 30 yrs ago because of immobility. You need to see a gastranterologist. They can figure it out usually.

Thanks for you suggestion regarding a backwards stretch. It does help a little, but my spasms are constant while standing.

Um starting to.worry about it

I Have only the leg and hip,maybe the stomach, and they happen at right
3 or 4 times only. Now im getting dizzy when i! get up whenever i lay down. Day or night seen my regular Dr yesterday nothing done yet.
