Muscle and joint pains or constant illness that is chronic or long term can be toxicity or insufficiency. If these are overlooked, it will stay constant. Chiropractic adjustment is not the sole answer to this.
This is why some people are adjusted over and over and do not resolve. Brain fog, constant tiredness, fatigue, headaches, depression and just giving up normal life activities can be toxicity & deficiency. Long term symptoms like these lead to degeneration of joints, organs and brain.
