Stay Hydrated
Drinking sufficient fluids during the day is important to alleviate arm pain. This is especially after working out or doing intense physical exercises. Dehydration would lead to a wide range of issues, including arm pain and muscle soreness. Basically, you should aim for at least 2 liters on a daily basis. The amount should be more when you are engaging in physical activities. Avoid coffee, tea, and other caffeinated drinks because they would bring diuretic effects, meaning that your body would lose fluids quicker. [6]
