My autoimmune problems started before I even knew they existed. This is often the case because you may have an autoimmune condition up to 15 years before you are diagnosed. Someone may have antibodies 5, 10, 15 years before diagnosed, often with no symptoms. At some point when I was 18 my body started this process.
Has your doctor ever prescribed dry brushing? When I was suffering from some inflammation my Functional Medicine doctor had a quick response and it was dry brushing. It is now part of my routine thanks to Dr. Caroline Schier!
