Thermacare Lower back Heat Wraps (2 x 2 Pack = 4 Wraps)

Unlike other creams, rubs and patches, which create sensations on your skin to mask pain, ThermaCare HeatWraps use real heat therapy to accelerate healing and relieve pain at the source for up to 8 hours, and once removed, another 8 hours - that?s 16 hours of relief from aches and pains.
