I am so excited to be seeing Dr Greenberg! He is an angel that has entered my life, and I am so very grateful to be his patient. After 8 years of dealing with dozens of doctors, as many surgeries, countless prescriptions and various methods of treatment to treat my post-mastectomy chronic pain in my chest, armpit, upper arm and forearm, I am happy to shout to the treetops that I am pain-free! His compassion and concern were primary, his mind going quickly to what he could do for me.
