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.
In many cases, a pinched nerve as a result of an injury will go away on its own, or will only require anti-inflammatories, hot/cold therapy and a little rest. However, a pinched nerve caused by a degenerative spine condition may require more extensive treatment. Outside of a minor injury, a degenerative spine condition is the most common cause for a pinched nerve. As we age, our spine naturally begins to deteriorate as a result of regular wear and tear and weight gain.
