If you look at someone from the side, you notice that the spine is shaped a little like an "S"...
The low portion of your back is called the lumbar area. What the above means is that the lumbar area of this "S" shape in straightened --or flattened-- thus producing a straightened lower spine...
It usually occurs with back spasms, but maight not really be important...
The spine is shaped like this to allow better balancing for standing.

Cervical lordosis is a curvature of the spine and, most of the time, it is an inherited condition. It can also be caused by an injury to the neck. Loss of cervical lordosis can be caused by heredity, injury and/or trauma, osteoporosis, obesity, and stress and strain to the neck. It can also be caused by poor posture. It can be treated chiropractic, physical therapy, or surgery.
Cervical lordosis refers to the curve in the spine at the level of the neck. Normally it curves backwards, with the convexity toward the front of the body and the concavity toward the rear.
So, a more pronounced curve than normal would be "increased cervical lordosis". Since the shape of the curve is maintained by the background tension of the supporting muscles, if the muscles grew weak and lacked tone, the cervical spine would sag, and lordosis would increase. On the other hand, decreasedcervical lordosis usually means the muscles are too tight, as in spasm, and are pulling the curve of the neck to be more straight.
depending on how long the bulging has been, typical first signs are tired and stiffness of the neck, followed by head aches, which start of at the back of the head at the occipital region, which then travels up to the top of the head before creeping down the to the temple and across to the eyebrows. you may also experience constant sleepiness from the decreased blood flow from the bulge.
bulging cervical disc typically occurs at C3 to C5 and will also result of stiff shoulders, given sufficient time, twinges that progress to numbness, starting from the shoulder to the acrominal (point of shoulder) to the brachial (arm) to the Antecubital (front of elbow) and finally down the forearm to the hand where its finally finishes at the thumb, index and middle finger. if reached at this point, typically the bulge has happened for several years provided its not a serious one.
numbness at the pinky, ring and middle finger occur from thorasic (chest/back) C7-T1-T2 and travel from the back of the arm, opposite from the cervical path
Lordosis is the normal curvature of the cervical spine. A normal lordosis is not expected to cause any symptoms.
Lordosis is a curve in which the anterior (or front) of the spine has a convex curvature, and the posterior spine (or back) has a concave curvature. Measurements made from radiographic studies (x-rays) may demonstrated abnormalities of a normal cervical lordosis, such as: hypolordosis (a reduction in the normal curve), hyperlordosis (an increase in the normal curve, or cervical kyphosis (a reversal of the normal curve).
The lumbar spine also has a lordotic curve.
