Lumbago - Sciatica - Backache
Almost everyone knows what is back pain. Lumbago is one of the most frequent problems: it is the second cause of medical visits after influenza and it has been estimated that 4 on 5 people suffer from it sooner or later in life.
The spine is made by vertebras , separated by intra vertebral discs that act as shock absorbers , and its stability is assured by a group of ligaments and muscles.
Inside the spine it is located the spinal marrow from which the nerves source and, coming out from spaces between a vertebra and another, they reach different parts of the body.
The lumbar section of the spine, composed by 5 vertebras, is involved in almost every movement: it is fundamental to hold the back straight, to allow the torso rotation and its flexion. The back sustains most of the body weight and efforts and if its functions are compromised this can be strongly invalidating.
The main symptom of lumbago is obviously pain that can locate in a specific area of the back.
It is often provoked by a muscle or ligaments sprain and it usually shows up together with a trauma, also called back strain.
Pain can be continuous and can sometimes ease by changing posture or practicing a light physical activity.
It is recommended not to practice heavy physical activity because it causes the symptoms to increase. When pain is provoked by a compression of one of the nerves' roots that come out from the lumbar spine, it tends to irradiate to the area reached by the entire nerve.
So, if speaking of the lumbar spine, pain reaches the lower limb on the interested side of the body. In these cases the result is lumbar sciatica.
Ache may be felt after making an effort but also spontaneously and tends to be continuous and characterized by peaks of pain.
