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 treatment of a pinched nerve depends upon the location and the cause. Resting the affected area is often very effective, especially in cases of injury caused by repetitive activities. Physical therapy is frequently beneficial when a pinched nerve is caused by problems in the neck or low back. Exercises may strengthen the back or core muscles and decrease or eliminate pressure on a nerve root. Over-the-counter anti-inflammatory medications like ibuprofen and naproxen may be helpful. Injections of corticosteroids (an anti-inflammatory medication) may also be beneficial for many types of pinched nerves. For cases of carpal tunnel syndrome, splinting or bracing the wrist is often used.
