I am lucky enough to have an excellent GP (General Practitioner) who takes me seriously indeed, because he both read about 40 pages of my health/pain diary I gave him, and knew that when I quit my job I must have been really desperate (to give up a secure job when I had no money, savings, assets and over $30,000 of medical debts and monthly rent to pay). He has referred me to a number of specialists, most of whom have been unhelpful for FM/CFS (except for my excellent Cardiologist, Endocrinologist, Neurosurgeon, Orthopaedic specialist etc who are/were treating me for non-FM/CFS related health conditions or surgery).
My GP has bulk-billed my consultations to Medicare from the early days when I started seeing him about 12 years ago and continues to refer me for path/xrays/scans etc which can be covered by the Govt Medicare system here in Australia (non private labs etc which will put me out-of-pocket). He has an excellent 'bed-side' manner and is always willing to listen to any of my theories, or knowledge on subjects of which he may be lacking.
He has never said "it's all in my head" and I think his support has been one of the most important aspects of my 'treatment'.
Finding a supportive primary care physician who is willing to listen and co-ordinate specialist health care is probably just as important as specialists in any particular field of medicine.
To this day, He, and only He, is truly compassionate and understanding of what is like to live with chronic pain and fatigue and a plethora of other debilitating health conditions.
