Hello, I read carefully your query and understand your concern. Anxiety can cause muscle twitches and spasms, too. Typically, the anxiety causes stress and that stress can put tension on muscles and nerves. That can disrupt body signals which causes certain muscles to react with involuntary movement. So, I sugest to lower the stress in the daily basis and have a healthy lifestyle. In my opinion, probably it is nothing to be worried. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards! Dr.Dorina Gurabardhi General &Family Physician
