Trouble Moving or Walking
Do you feel stiff in your body, arms or legs? Have others noticed that your arms don’t swing like they used to when you walk? Sometimes stiffness goes away as you move. If it does not, it can be a sign of Parkinson's disease. An early sign might be stiffness or pain in your shoulder or hips. People sometimes say their feet seem “stuck to the floor.”
What is normal? If you have injured your arm or shoulder, you may not be able to use it as well until it is healed, or another illness like arthritis might cause the same symptom.
