Begging doctors for tests, I worried that I was missing something and heading for an early death. Would understanding the roots of my health anxiety lead me to a cure?

hroughout my adolescence and into my mid-20s, I spent a lot of time trying to understand my body. I was unwell, that much was certain. The question of exactly what was wrong with me was one to which I applied myself studiously. I had theories, of course. Looking back, these tended to change quite frequently, and yet the fear was always the same: in short, that I was dying, that I had some dreadful and no doubt painful disease that, for all my worrying, I had carelessly allowed to reach the point at which it had become incurable.

This started at university, when I developed a headache that didn’t go away. The pain wasn’t severe, but it was constant – accompanied by a strange feeling of belatedness that told me it had already been going on for some time. How long, exactly, I couldn’t say – weeks, definitely. Maybe it had been years.

After about a month, I visited the doctor. She had an earnest, warbling, confident way of speaking, which, in spite of her evident commitment to the tenets of mainstream medicine, gave her the air of an alternative healer. She explained that what I was experiencing were tension headaches, a common ailment among students, and during exam season practically universal. I said that I didn’t feel very tense. The doctor asked whether the pain felt like a tightness across both sides of the head. A kind of squeezing? Like an elastic band being pulled tight? Like a fist clenching around your skull? I said that it did not feel like these things. Yes, she said, nodding meaningfully. Every person experiences tension differently.
