hi Megan, you have been left high and dry by this doctor. You would expect at least some sort of advice on where you go next.
There are some funny attitudes in the medical fraternity towards illnesses with which they are not familiar, or which they don't believe exist.
Easier to say it is all in the mind than try to treat a difficult illness!
I suggest that you read up on Fibromyalgia, find a good and reputable symptom list, and then compare yourself to it.
You then need a diagnosis guide to see if you meet the criteria.
Armed with this, see your GP.
You may be able to find a Fibro group who could recommend a knowledgeable GP.
My daughter has ME and as far as we can find out, there are only two Perth doctors who will treat patients with it.
Once again, there is a lot of disbelief and confusion about this illness, and it's not helped by insurance companies employing doctors to say it is psychological, not physical, thereby avoiding a lot of payouts. Very sad but true.
