I will try and make this as to the point as I can. Every negative symptom you have from any illness or negative symptom from exposure to toxic elements are symptoms of a congested (acidic) lymph system.
The lymph fluids are not contained in just the lymph nodes. Lymph fluid surrounds all your organs and muscles, which explains the aches and pain we get when the fluids are acidic.
I feel sure Medical Doctors have a different definition of a congested lymph system which may include swollen lymph nodes but I'm explaining from pH balancing principles, ala moreless......but I feel certain you are here to learn the moreless way and not the medical way....am I correct?
