@fiesty76 -- one other suggetion, Fiesty, for your friend. She needs to be very careful about getting scratches or scrapes on her affected side. When I do my gardening or if I know I'll be hiking in a brushy area, I wear a long arm protection sleeve made with Kevlar. She may also find them at a gardening shop. Even something simple as a bug bite/mosquito bite can cause a person sensitive to lymphedema problems. So since she has already had cellulitis, best to err on the side of caution -- not to be constantly afraid of hit happening, but being vigilant. All the best.
