Unfortunately your story is all to common an occurance. I too have been ill for over 7 years now with too many doctors scratching their heads not knowing what on earth is causing my problems.
As for the psychological, after such a long undiagnosed or unsuccessful treatments you do begin to think it's all in your head. After all, if it wasn't they would have found it right???
Not always the case. The last time I went through this nonsense I was in and out of hospitals for 6 years and after freaking out at the pain they did a cat scan and discovered I had a tumor that even the scan did not show all of it.
Psychologically there is an impact on pain. The old question is, which came first. I had that wonderful emerge visit where a dr said, I needed a shrink. I called her bluff and told her yes, but get me the best because I had already been assessed and was told this was not psychological. My neurologist laughed and her explanation to me was this.
There is no doubt that there is a psychological component that can aggravate the pain however it is not the cause of my unknown problems.
Thank you Doc!
Don't give up on the medical profession. Unfortunately, you may have to weed out the bad apples who don't want to take the time to figure it out before you find one that really likes the challenge on we difficult cases.
My newest doctor has been open and very compassionate in his admission that he just doesn't know what is going on, But he hasn't given up. While that doesn't get rid of the pain, it goes a long way to helping my psyche.
I do the best I can because I know the impact on everyone around me and the frustration they feel at the length of time it is taking. Hang in there! Sooner or later your body will show them what they need to know.
One thing my neurologist suggested was to keep a diary of the pain, where, intensity, description etc. After a year of that it helped her to see a pattern that individual appointments weren't really showing her. There were so many that I could not describe all the pain flair ups with the details that my diary gave her.
God Speed in finding a good Dr. and the path to a better way to cope.
