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.
Some women begin to experience pregnancy symptoms as soon as they conceive while the others take few weeks to develop pregnancy symptoms. Experts are of view that pregnancy symptoms begin in 5th to 6th week of fertilisation. Even though some women say that they noticed changes in their body within a week of unprotected sex. Others miss the signs for a 3 or 4 weeks. When the egg is fertilised, it becomes attached to the uterus and starts to produce hCG.
