People with arthritis and bursitis can experience pain and discomfort when performing everyday activities. Applying lotion to their shoulders and back can prove to be challenging and even painful, but a body lotion applicator can help. The applicator has a long handle, making it easier to reach the back. There are several types; some applicators have rolling balls while others use a roll on application. They can be purchased through online websites such as Bed Bath & Beyond, Active Forever, Maxi Aids and Life Solutions Plus. Prices range from $6-$20 depending on the make and model.
