I know exactly how you feel - frustrating isn't it?
Being assertive and knowledgeable didn't get me anywhere with my GPs.
Being humble and respectful didn't get me anywhere with my GPs.
Being upset, desperate and at the end of my tether didn't get me anywhere with my GPs.
Trying to discuss my many symptoms didn't work - my GPs had an 'explanation' for them all. I would have laughed at them if I wasn't so miserable.
All I was offered for my symptoms, fluctuating TSH and raging antibodies was a 'trial' of thyroxine 25 mcg.
That was 2 years ago and when I said that my symptoms were no better I was 'allowed' an increase of 25 mcg every other day because 'any more and we would definitely be over treating you'. I was refused a referral to an endocrinologist as there 'was no need'. I was refused more blood tests as there 'was no need'.
I considered making a formal complaint to the practice manager about one of the GPs in particular who treated me with contempt and reduced me to tears of frustration several times. However, like many others who have replied to you, I knew it would not help me and that I had to be responsible for my own health. I was not just going to 'fade away' like many others probably have had to.
Like you, I am an intelligent, educated woman with a professional medical background. I did my own research on line, reading books and learning from this forum. I also listened to my body and reflected on my health over the last 10 years (since my diagnosis of fibromyalgia). It all fell into place and I made my own diagnosis.
I did a few private blood tests to confirm this, monitored my pulse and body temperature throughout the day and, because I suspected a degree of adrenal fatigue, made an appointment with Dr P. He confirmed everything I 'knew' and I am now working towards getting better - without the NHS. And yes, I buy my own meds.
We are all different and I don't feel I can give you advice but I hope you find out as much information about this illness as you can, don't accept your GP's concept of 'normal' and take matters into your own hands if you have to.
Take care of yourself and stay determined xx
