A negative pregnancy test can occur when you have a late period and are not pregnant. Your menstrual cycle is under hormonal control. The ovary usually releases one egg (ovulation) each month, and about two weeks after, the uterine lining sheds, resulting in menstruation.
In many cases a pinched nerve can be treated with rest and ice. If the pinched nerve is in the arm (carpal tunnel syndrome or cubital tunnel syndrome) the doctor may recommend a brace for a short period of time. The brace limits the amount of movement around the nerve, which allows it to rest and recover.
A pinched nerve occurs when too much pressure is applied to a nerve by surrounding tissues â such as bones, cartilage, muscles or tendons. This pressure disrupts the nerve's function, causing pain, tingling, numbness or weakness. A pinched nerve can occur anywhere in your body. A herniated disk in your lower spine, for example, may put pressure on a nerve root, causing pain that radiates down the back of your leg (sciatica). Likewise, a pinched nerve in your wrist can lead to pain and numbness in your hand and fingers (carpal tunnel syndrome). With rest and other conservative treatments, most people recover from the effects of a pinched nerve within a few days or weeks. Sometimes, surgery is necessary to relieve pain from a pinched nerve.
