Can gas cause painless muscle spasms?

Yes, gas can cause painless muscle spasms.

Gas can accumulate in the colon and put pressure on the surrounding muscles, causing them to spasm. These spasms can be felt as cramps and can be painful, but they can also be painless. Painless muscle spasms may also be caused by a lack of electrolytes, such as magnesium, potassium, and calcium.
