My neck looks short. How about trapezius Botox?

Since I spend all day at the office typing with my head down, the back of my neck and shoulders are always stiff as rocks. My trapezius muscles are gradually bulging upward, making the nape of my neck look thick, and my collarbone line is obscured, so my upper body looks heavy and bulky when I wear clothes with wide necklines. Even after getting massages and scrubbing with a foam roller, they tighten up again the next day, so I felt I needed to fundamentally release the muscle tension. I want to smooth out my shoulder line and reduce the stiffness, but I would like to know from reviews whether the procedure causes my arms to lose strength when lifting heavy objects or interferes with daily life. Thank you in advance for your answers.
