In our current age of anxiety, medical-themed TV shows and WebMD, most of us — at one time or another — have inflated a pimple into cancer or a stomachache into appendicitis.

But few of us can match Jennifer Traig’s obsession with self-diagnosis. As we learn in “Well Enough Alone,” Traig has imagined herself to have every fatal or debilitating disease known to medicine. “The skin cancer turned out to be ballpoint ink; the meningitis, hay fever; the pancreatitis, too many candy bars; the blood poisoning, ill-fitting shoes,” Traig writes.

However, the subtitle of Traig’s painfully frank and very funny memoir is somewhat misleading. Yes, Traig is a hypochondriac, but she also has plenty of very real problems. Readers of Traig’s first memoir, “Devil in the Details: Scenes From an Obsessive Girlhood,” know that Traig suffered from obsessive-compulsive disorder (OCD) and eating disorders as an adolescent. In her latest book, we learn that she has since contended with tremors, severe eczema and irritable bowel syndrome, among other ailments.

Luckily for Traig, none of the illnesses she details in this book are life-threatening, but nearly all are both unpleasant and mortifying.

But Traig’s brutally honest and wickedly funny voice carries the story. As a bonus to readers, the book’s “appendix” features a health horoscope and translations of handy phrases — including “Hello! I think my spleen is infected.” — for hypochondriacs traveling abroad. Because, hey, you never know.
