My right hand muscles not working properly since 1 year im not able to lift weight from right hand. Which type doctor should I visit? And what is the problem I have?

Question

Warm up before exercising.
Stretch daily to improve your range of motion and flexibility.
Rest after exercising. Take days off or work different muscle groups on different days.
Strengthen your deltoid muscles so they can handle more strenuous exercise. You should also strengthen your core so that it can help support your shoulders while you exercise.
If you work at a computer, make sure your keyboard is positioned so that your shoulders don?t strain up or down when typing.
Practice good posture.
Desk angels
sitting straight in your chair with perfect posture, place your arms at shoulder level with a 90-degree bend in your elbows.
Keeping your head and torso stationary, slowly move your arms overhead, reaching your hands toward the ceiling. Try to keep your arms in line with your ears as you move up to the ceiling and slowly back to the starting position.
You should feel some pulling in your midback, which helps to relax your spine.
Repeat 10 times.
Shoulder rolls
keep your back straight and your chin tucked in.
Roll your shoulders forward, up, back, and down in a circular motion.
Repeat 10 times, then reverse.
Upper trapezius stretch
sitting with your back straight, tilt your head sideways toward your shoulder.
For a larger stretch, drop your shoulder blade on the opposite side toward the floor.
Hold for 10 seconds.
Repeat twice on each side.
Armpit stretch
this stretch will make it look like you?re trying to smell your own armpit, so perhaps you should perform this one when you?re sure no one is looking.
Sit with your back straight.
Rotate your head sideways so that your nose is directly above your armpit.
Hold the back of your head with your hand and use it to gently push your nose closer to your armpit. Don?t push to the point of discomfort.
Hold for 10 seconds.
Repeat twice on each side.
