I know my mental health as deteriorated over the last 8 or 9 years ever since an severe episode of depression. In another thread on here Ive spoken about pain/irritation in my head and feet. I've had this to some degree earlier on in my life as a teenager with feelings of contamination leading to irritation in the area affected.
If only it was so dam easy to get doctors to refer you for a CT scan or something. It would answer SO many questions.
