Abdominal muscle cramping

[Pompeybrutus]

Hi
not sure if anyone can help. Since having my son 14months ago I have been periodically having these muscle cramps in my abdomen. They aren’t IBS. I can see my stomach muscles moving and contracting / twisting on their own.

has anyone had any experience of this. It’s really painful. Happened today whilst at a soft play with my son and afterwards it’s like I’ve done 1000 sit ups

Have you had your iron checked recently?
I had this as a weird symptom of anaemia, I had to have infusions as my levels were so low but since then I’ve not suffered from them.
