Will a breast reduction really help reduce back pain?

Most likely. Getting the weight off of your shoulder nd back after a breast reduction often helps with back discomfort . My reduction patients are some of my happiest.
It depends. If your back pain is being caused by the large breasts then it will be helped. It has been my experience that neck and back pan in between the shoulder blades is helped the most after breast reduction. If you are over weight then loosing weight may help your back pain and reduce the size of the breast.
Yes. Upper back and neck pain is often dramatically improved after reduction of very large breasts. This does not apply (in my experience) to lower back pain.).
