When an individual has a pinched nerve in the lower back, for example, symptoms of pain will usually radiate down the leg. A pinched nerve in the neck can cause pain to travel from the neck, through the shoulders, down the arms and into the hands. Muscle spasms in the back commonly coincide with pinched nerves and can cause weakness in the arms or legs. The two most common pinched nerves in the lower back are L5 (lumbar 5) and S1 (sacral 1).
Most pregnant women start to get the queasies when they're about 6 weeks along, but some can experience morning sickness (which unfortunately can occur morning, noon and night) earlier. It will most likely subside as you enter the second trimester.
Last updated: December 2016. Could you be pregnant? Some early pregnancy symptoms may show up around the time you've missed a period â or a week or two later. About 60 percent of women have early pregnancy symptoms by the time they're 6 weeks along, and roughly 90 percent have them by the time they're 8 weeks.
