Yes , it is clear that treatment to the complained of structure in situations when the pain is neuralgic , will provide brief periods of relief. exercise in general will induce positive changes to the lumbar protective behaviours that had been the direct cause of that neuralgia. In 25 years of consideration of MSK complaints such as the one mentioned, "bursitis" of any kind is rarely, indeed , very rarely the real diagnosis. In most cases the "diagnosis" had been made without any or adequate consideration of central ( spinal ) mechanisms.
