The Balm Box Side Protector Under-Arm Pillow | CVS
This clever pillow is specially designed to fit under the arm to redirect arm friction away from tender torsos, while cushioning the back. *Consider purchasing two if undergoing a double-mastectomy. The weight of the arm can irritate a cancer patient's upper torso, especially after mastectomy* or lumpectomy surgeries, as well as during radiation treatments..
