I actually never knew stress until I started dealing with Doctors. Oh, I had the stress of life like others, a divorce
when young, the death of a father, a brother, ect., but none caused my body to go into pain.
Usually it a patient complains about pain and the Doctors keep saying it's psycosomatic pain they will send you to a psyco/neuro therapist. This person is trained to determine if the pain is real or psycosomatic and most are good.
