The Volas Inflatable Lumbar Reliever, Adjustable Air Bag Waist Support Plate to Relieve Lumbar Disc and Waist Stretching Artifact Wholesale title mentions relieving a lumbar disc. The bullets mention back discomfort, tiredness and spinal alignment.
Those phrases are not used here as medical results. Do not skip a clinician. The product, if you buy it, is a listed inflatable support plate in Gray or Blue.
Open the Volas lumbar listing for the written bullets only.
