There is no single regimen that can be considered as the best treatment for lower back pain. Various kinds of back pain causes and varying the severity of each cause requires special care methods adjusted to each individual condition. Thus, it is difficult to say just rest, treatment or surgery can be considered the best option to treat lower back pain for each single case diagnosed.
Of course, from the perspective of preference and comfort, doctors hope for rest, therapy and other non-invasive treatments will be enough to treat lower back problems. This is because prescribing rest, therapy and pain medication implies that the condition has not progressed beyond the point where it already requires surgery. For doctors and patients, this is good news. After all, no one wants to risk operations given all potential complications that might arise from the procedure.
However, there are also times when surgery is the best treatment for lower back pain and no other method will be enough. This is usually because the hernia disk is quite damaged so that it permanently suppresses nerve roots around its location which produces extreme and continuous pain. When this happens, rest or treatment may not be enough to treat these conditions.
