I feel the need to post this because I see "quality of life" being used as a catch phrase that obfuscates a more important issue, longevity.
Pain serves a biological purpose, the avoidance of injury and the avoidance of injury aggravation. For example, it would be bad for someone to walk with a broken bone in their leg. But, sometimes the cause of pain is not aggravated (at least, not permanently) by exercise. Correct me if I am wrong, but, it is my impression that, most typically, the causes of sciatica and piriformis syndrome are not aggravated by walking or running even though the pain temporarily increases. I am less familiar with other kinds of spinal pain but I strongly suspect that often walking or running do not aggravate these injuries even though the associated pain may temporarily increase during exercise. Right?
When there is no injury aggravation, exercise is good because it increases longevity. Right? Often pain medications allow exercise that would be difficult or impossible otherwise. Right? Under this circumstance, pain medications can increase longevity. Right? This is a life or death rather than a quality of life issue. Right?
Have you thought about it before? What are your thoughts?
