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.
Any time you have sex, there is a chance you could get pregnant. Pregnancy symptoms differ from woman to woman and pregnancy to pregnancy. One of the most common symptoms is a delayed or missed period. You may see signs of pregnancy within a week of conception. It is also possible for symptoms to start a few weeks later. If you think you could be pregnant, watch for these early signs and symptoms 1: missed period, headaches, tender breasts, nausea, and lower backaches. Unfortunately, these symptoms are not unique to pregnancy, and you could be pregnant without experiencing any of them.
