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.
When Do You Start Showing Pregnancy? The answer to the question actually depends on the growth of the uterus. Most women notice the baby bump between 12 and 16 weeks of pregnancy. This is because the 12-week uterus has stretched up and above the bones in the pelvis.
