Lower Neck Pain Pain In Lower Neck Between Trapezoids From Shrugs?

Pain in lower neck between trapezoids from shrugs? - lower neck pain

I began my training harness, but now it's painful to look at. The lower neck, right before the shoulder blades, where the pain is not a kind of muscle pain, usually receives damage after exercise. I do 3 sets of different weights with representatives of 12 years. The weight is 27 kg, 30 kg and 32 kg. What am I doing wrong and how can I prevent my neck the wrong way?
