People have suffered from back ache since ages. It is the world’s most common problem that men and women of almost every age are suffering. Even the kids are now complaining about this trouble as the reasons of this pain are commonly visible in them as well. But most commonly, this pain is among the older people who have suffered a lot of heavy work all their life and even some of them have been complaining about it since they remember.

Treatment may vary depending on where the pain is and also on the severity of the pain.
Lower left back pain is very common among those people who are in a habit of working a lot at their desk, who sit in a very uncomfortable chair, probably hunch over to complete their time consuming assignment at the office which their boss have assigned them, sit in an awkward posture while working at their computer, lift heavy objects or give their body a sharp sudden twisting or bending movement, have suffered some kind of accident, have a left kidney problem or if any women is pregnant etc. Wear and tear of the lower left side muscles might also incur stress and pain in that area. You need to understand its causes before start treating it. 
The pain may start as dull or intense pain in the lumbar spine region or shooting from the back to the thigh and buttocks. An important fact that you must keep in mind is that you must not neglect it as if this pain lingers on, it would move towards your legs and buttocks and into the abdominal muscles which are the real saviors. And if this pain moves to these parts then it would be really difficult to control it and it would also cause a great obstacle in your body movement which would ultimately result in an inability to complete your daily routine tasks.
Patients that are suffering from lower left back pain might be suffering from kidney problems. The pain experienced by those who are suffering from right kidney problems might be the same as that of left kidney patients. It depends on the severity of the problem. This problem should not be treated as it is of pulled or strained muscles because wrong treatment of the problem might aggravate the back pain. It might put more strain on the muscles and doing the wrong stretches and exercises might create more damage. People also come across this kind of pain when they are sitting or standing in a specific position. They must be vigilant of their body postures and avoid those positions which invite more pain on their lower left side of your back.
The treatment of lower left back pain and lower right back pain is often the same depending on the symptoms that are faced by both sides. The most important thing that you need to keep in mind is that you must not let your acute back pain turn into a chronic one, otherwise it would become untreatable. A chronic pain means that it lasts more than three months and causes problem to other regions of your body as well. The most readily recommended treatment for such back pain are stretches and exercises. Medications, injections and surgeries are the last resort because they have their own side effects.
