A member asked:

I have some twitching in my lower left back it's painless, just annoying at times. could it be something to worry about or maybe a zoloft (sertraline) side effect?

A doctor has provided 1 answer

Unlikely: Painless recurrent localized muscle twitching is typically related to fatigue or mild physical stress in the area of the twitch.
