I keep getting a bad back at the bottom and its really painful i cry it hurts that much i'm wondering if a breast reduction would solve this problem?

Possible: It is possible for very large breast to cause a back strain. I am more concerned with the severity of your pain. You should see a back specialist to have a thorough evaluation. www.drlugo.com.

Perhaps: Very large breasts (upward of ddd cups) may cause back problems, although they are usually upper to mid back, or between the shoulder blades. See a plastic surgeon for an evaluation, the consultations are usually complimentary, and of you have insurance they should pay for tho type of surgery.

Talk to your doctor: You need to be evaluated to understand the cause of your problem, breast surgery may be of benefit but there may be other problems.
