After I taken off my bra, they leave dents on my shoulders & soreness. Do I need a Breast Reduction or a Breast Lift? (photo)

Since your breasts create dents in your
shoulders and soreness, you are an excellent candidate for a new technique
called The Ultimate Breast ReductionTM.This technique reshapes your breast tissue
creating upper pole fullness, elevates them higher on the chest wall and more
medial to increase your cleavage.The
weight of the breast is transferred to the underlying muscle resulting in
immediate relief of neck, back or shoulder pain without excessive weight
reduction.This allows the woman to
choose the size breasts they want rather than undergo excessive reduction to relieve
pain.The Ultimate Breast ReductionTM
avoids the ugly vertical scars of the traditional technique, maintains nipple
sensation and the ability to breast feed.Best Wishes,Gary Horndeski, M.D.

Based on your history and photographs you appear to need a reduction mammaplasty.  A breast lift alone is a skin removal operation which will leave you with excess breast tissue and will not likely relieve your symptoms.

  If you want the pressure to be relieved, a breast reduction would make more sense.Kenneth Hughes, MDLos Angeles, CA
