9Rest
The cause of upper arm pain can be overexerted muscles, such as lifting heavy objects or repetitive movements. In these cases, resting is a simple way to recover. You need to stop using the affected parts for several days until your symptoms improve. If the issue is related to work, advise your manager to make a temporary switch to other tasks. However, you should not rest on the bed the whole time. Some movements are necessary to stimulate blood flow and speed up healing. [9]
