Breast Reduction and Pain After Chiropractic Treatment?

If there was undue pressure put on your breast during the manipulation it is possible that you suffered some trauma. If you're concerned about something specific bring it to the attention of your surgeon.

I would think that the pain would not be related to your breast reduction but it is hard to diagnose with out a physical examination.  I would start with your chiropractor since this is when the pain occurred during a manipulation. 

It is unlikely but not impossible that pressure cause a problem.  It is more likely associated with your musculoskeletal system as opposed to the breast itself. Discuss this matter with your surgeon and chiropractor. Best wishes.

At six months after a breast reduction, I think it would be highly unlikely that anything was injured.  If you are concerned, I would suggest seeing your surgeon.
