You can rest your pinched nerve and still keep your blood pumping. Good blood and oxygen circulation and toned muscles can actually help heal the pinched nerve.  Daily activity should be done conservatively and only when it is comfortable for you. Try going swimming or for walks. These will help to move your muscles naturally while placing a minimal amount of stress on the joints and tendons where the pinched nerve is.  Inactivity can lead to a loss of muscle strength and cause the healing process of the pinched nerve to take much more time.  Keep good posture when exercising or resting. This will help to ease tension at the location of the pinched nerve. Maintaining a healthy weight can help prevent a pinched nerve. One of the underlying factors of a pinched nerve is a calcium deficiency. You should start eating more calcium rich foods such as dairy products like milk, cheese, and yogurt and leafy greens like spinach and kale. This can help the nerve and also improve your overall health.  You can also take calcium as a supplement. You can buy these from many health food stores, general stores, or pharmacies to take on a daily basis. Follow the directions or consult your doctor if you are unsure of how much calcium to take. Never take more than the recommended dose. Check labels of packaged foods to see if they are calcium fortified. Many brands offer a calcium enriched product in addition to their usual products. Potassium is a key ion involved in cell metabolism. Because it causes weaker connections between nerves, a lack of potassium can sometimes contribute to symptoms of a pinched nerve. Increasing potassium in the diet may help to restore proper balance to your nerve function and alleviate your symptoms.  Foods rich in potassium include apricots, bananas, avocados, and nuts. Drinking fluids like skim milk and orange juice can help to increase potassium absorption. Potassium supplements, similar to calcium supplements, can be taken on a regular basis in addition to a healthy diet. Talk to your doctor...
