I am a 22-year-old female, I will be turning 23 in a few months. For over two weeks I have had a persistent twitch on my left eyelid. The twitch feels like a pulsating sensation, and I can sometimes trigger it by blinking hard or quickly blinking many times. Although I have not noticed any weakness, I have been having some tightness and swelling on my left shoulder for about a week and the trapezius muscle on my right shoulder appears smaller than the trapezius muscle on my left shoulder. I also recently had some swelling and mild pain in my left temple after coughing hard but it has since faded. I also get random jerky twitches all over my body (mostly on my lower legs, thighs, arms, torso, etc.) but these twitches do not have the pulsating feeling that the other twitches too, rather they are more like sudden sparky twitches. It might be worth noting that the eyelid twitching began during my menses and shortly after my menses ended, I caught COVID-19, which I am currently recovering from.
