I did have the twitching muscles that started around 1 yr post removal for me. It was the weirdest thing. It also was in my left bicep and both thighs. It did fade away after a few months. I didn't have the numbness or tingling. Another twitch I had that was even more annoying was an eyelid twitch that was practically constant for a few months. It started the same time I quit Zoloft, so I'm thinking that may be the reason, but who knows. I used to only get that when I was under alot of stress, so maybe the twitching is related to stress? Hopefully your new symptoms will go away soon!
