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.
The best you can do when you have a pinched nerve is to address the muscles, tendons, and ligaments surrounding the distressed area. In most cases, the cause is that the surrounding tissue has become inflamed and stressed from some injury. The main treatment options are physical therapy, massage or even medication. When treating a pinched nerve, it is important to locate and isolate the source, as it can occur in any area of the body. For example, a herniated disk can cause sciatica pain to run down the back of the leg.
