Abductor pollicis brevis twitches when palm abducts

[loverunning]

Hello

I have constant twitching in the abductor pollicis brevis muscle esp. when I try move my thumg away from my palm. It started about 5 months ago and not persistent. When it happens it is there for about a week and the not there for next 2 weeks. I have seen hand surgeon who did MRI and found writst ligament tear and some tendonitis (on the non-palm side). I have also seen a neorologist who says there is nothing wrong. I am really worried. Hand surgeon nevertheless gave me cortizone shot in the wrist 3 days ago. I am really concerned. Have any of you seen this type of case where the twitches (about 7-8 for say 10-15 seconds) when thumb anducts away from palm

Thanks

It could be from over exertion. I know that if I extend a toe or finger too much, this will cause it to tighten and not "retract" back into place for a bit, and will also cause tingling or spasms.
This could be the case, since you say that there was a tear in the ligament...it could have healed strangely.
