Clients concerns for markings vs clients concern for getting better!

Does anyone encounter issues with some clients in regarding to the sha that arises in cupping sessions? Many of my clients have the wonderful attitude that if it makes them feel better then 'cup on' they could care less about the aestethics; Considering my clientelle is 95% cupping, but I do have a couple that have purposely seeked cupping for chronic conditions and will complain of the markings that come up...how do you handle this in your practice?
