This is absolutely true and the care is completely individualized. I think I know about 30-40 patients of CFCD (from this board, other boards, and in real life), with about 4-5 who are very close friends, and each of us has a different treatment plan. Everyone will undergo similar initial blood tests to help assess what is going on but then they will treat what they find whether it's what I would call "classic" ME/CFS, any immune system issues (immune deficiency or autoimmunity), POTS & Dysautonomia, MCAS, Lyme & tick borne diseases, SIBO, EDS, or whatever they find. They will also coordinate with other doctors, with insurance companies, etc. I've actually never experienced anything like it and I have paid for expensive doctors locally who honestly didn't do sh*t to help me.
