Large Breasts- Mid Left Back Numbness/pain

I found no discussions about problems caused by large breasts.
I am seriously considering breast reduction surgery after decades of chasing solutions with little to no result.
The closest I've come to a solution is a gifted PT dancer who knows Pilates.

After reading a news article about Gokhale, I am ready to try one more thing. What is the first thing I should do to be evaluated?
Thank you,
Susan
