Tingling, numbness and weakness in arms.

I have been experiencing intermittent electric/buzzing or tingling sensations that start at one point and sometimes spread slightly along the area before fading. It happens at different times in my elbow, hands/fingers and sometimes my feet, even without hitting or putting pressure on them. I also sometimes experience significant numbness in my hands. My left arm feels weaker than my right and sometimes feels like I have less control, although I can still perform normal tasks with both arms. I have also had significant shoulder/neck pain for several months, along with headaches. I would like to understand whether these symptoms could be related to nerve involvement and whether I need any neurological evaluation or tests. (my screen time is more than 10 hours/day) Sitting Posture also not good
