I was surprised by how much I enjoyed this book, considering I just picked it off the shelf at random (the shelf wasn't random, though). I don't care that the Babylonians thought that toothaches were caused by magic worms sent by the gods, and the writing started out too lyrical for my taste. But once the book got into modern times, I was fascinated. It answered questions a friend and I had just been asking about the genesis of modern drugs (Tylenol was a pharmacist's mistake, and willow bark (aspirin) came into use (besides Hippocrates) because Rev. Edmund Stone reasoned that the wet dirt they grew in caused disease).
I was impressed by the depth of research. I can't recall another book which details an interview with a person ... and then follows up with the person years later. The evolution of a person's situation and attitude over time is very compelling, particularly if you "meet" them before the end of their story. I also got a kick out of reading about Dr. Sean Mackey of Stanford. I met the man for about 2 minutes, and he was intimidating and so brusque that the fellow later apologized to me for his manner. I fell over laughing reading about Dr. Mackey's study on the effects of infatuation on pain tolerance. *That* drill sergeant knows about puppy love? Anyway.
I liked that the author weaves in descriptions of her own journey with pain, and it was one of the better romantic stories I've read when she finally found a man who treated her well concerning her pain (unlike the series of douche bags she dated before). I also liked the longer term descriptions of some of the patients, particularly Dani who finally found relief with doctor number 85(!).
This book is palatable because it is not written for people with chronic pain. It is definitely not a self-help book. If you are in pain it will only make things worse, because there is very little good news.
I marked so many passages to remember that my book is bristling with sticky-notes. Here they are:
"In recent years, a new paradigm of pain has emerged [...]. The contemporary model of pain sees it as a complex interaction among parts of the brain. While founded on the same scientific traditions that gave rise to the nineteenth-century view, it has also revealed the truth embedded in the nonscientific, premodern model by showing the way in which pain is inherently meaningful because it is not simply a matter of nerves firing, but an experience created by meaning-making parts of the brain." p8
"When pain persists, these changes begin to be a source of pain themselves. Contracted muscles clamp down on nerves and cause pain. The rigid muscles cause postural changes that strain other muscles. Using the affected area hurts, so one guards it, which deprives it of exercise, which makes the muscles atrophy, which in turn makes it harder to use that area and causes more pain." p55
"Botched operations were the rule: in 1834 a surgeon generated controversy when he was quoted saying candidly that before a man could successfully perform cataract surgeries, he must first 'spoil a hatful of eyes.' [...] About a third of patients died from such surgeries." p93
"Unlike modern physicians, who focus on curing disease, ancient healers were primarily renowned for their anodynes. [...] only a few were true analgesics: opium from poppies, alcohol, cocaine from the coca plant, henbane, mandrake (mandragora), deadly nightshade (belladonna), cannabis (marijuana), and salicylic acid (similar to aspirin) found in willow bark or dried myrtle leaves." p101
People used to calm babies with syrups containing opium (p102)
"Although there is a scientific consensus about the reality of the [chronic pain] disease, it has not gained widespread acceptance outside the small circle of pain specialists." p130
"A patient who comes in with twenty years of back pain is more than twenty times less likely to get well than one who comes in after just six weeks." p145
If their pain is still there but their doctor is nice, patients assume that there is nothing that can be done for their pain, and they say they are satisfied with their doctors. p153
"There is increasing evidence that both conditions involve abnormalities in the neurotransmitters serotonin and norepinephrine, which play a role not only in mood disorders but in the gate-control mechanisms of pain. [...] Pain decreases available serotonin (by increasing the rate at which it is reabsobed), which weakens the pain-modulation system, creates more pain, and creates depression. Thus, we can see that anxiety and depression are not merely cognitive or affective responses to pain; they are physiologic consequences of it. [... Dr. Beritbart says,] 'Seotonin facilitates descending analgesia' (the brain's ability to modulate pain in the spinal cord by stopping incoming pain messages), 'and chronic pain uses up serotonin, like a car running out of gas. If the pain persists long enough, everybody runs out of gas.' [...] To make stress reduction a primary strategy for pain treatment is like counseling a drowning person to relax." p157-158.
"In much of China and Africa, opioids are largely unavailable or prohibited." p 159
A meta-analysis of 25 studies put the average risk of opioid addiction at 3%, and 0.19% for chronic pain patients with no history of addiction. "'We live in a medical society that would rather prevent one addict from being formed than treat a hundred suffering,' Dr. Scott Fishman observes." p 161
Women and men react differently to the same pain medications (and many new medications are tested only on men, so the ones manufactured are the ones that work best for men). Redhaired women need more opioids than dark-haired women for the same analgesic effects. p176. Infants used to be circumcised without anesthesia (seriously?), p177. Chronic pain patients lose about twice as much gray matter per year as normal subjects, p186 People can be put off by doctors quoting statistics and refusing to be pinned down, instead of being reassuring.
"It has often been observed that male and female patients with complaints of pain are treated differently. Men are more likely to be given opioid medications, surgery, and complete exams, while women are given psychotropic medications for depression and anxiety. [...] Women tend to be either less aggressive in demanding pain treatment or aggressive in ways that are dismissed as mere hysteria." p 167-168 Thus the problem mentioned by women - if they present themselves as assertive and well-groomed, they are not perceived to be ill. If they don't, they are dismissed as a basket case.
Sophocles wrote, "One word frees us of all the weight and pain of life: That word is love." p202
"A significant percent of women used to complain of chronic pain following radical mastectomies. Their pain was often interpreted as a psychological phenomenon: they were just 'missing' their breasts. But in the early 1980s, Dr. Kathleen Foley [...] identified the pain as being caused by the severing of a major thoracic nerve during surgery." p218 So basically, up to the present day, unexplained medical problems are caused by "spirits" and women are crazy, until a (female) scientist finds the real reason.
"Studies suggest that one of the best predictors of whether a patient will adhere to a treatment plan is the patient's relationship with his or her doctor." p230
"'Build ... an illness narrative that will make sense of and give value to the experience,' the medical anthropologist Arthur Kleinman enjoins." p243
"Neuroimaging studies show that a placebo activates the brain's pain-modulatory system in a way that is neurochemically indistinguishable from treatment with an opioid analgesic. [...] The use of a placebo increases morphine's efficacy by more than a third (with the placebo in this example being simply the positive expectations created by telling patients they have been given morphine and will soon feel great relief.)" p292 "'It's a pregnant irony that striving for the placebo effect is a frank contradiction to what clinical practice is all about. It's frustrating that you can[t use this simple tool that works so well in experiments. But a relationship with a doctor is one of the most important human interactions. [...] And honesty is the foundation of that experience.'" Dr. John Keltner. p296
Acupuncture, which is used (sometimes) effectively for surgical anesthesia in China, seems to be largely hypnosis. p298
Dr. Mackey believes that functional imaging and genetic testing, with machine learning and other new technologies, will eventually help doctors to identify effective pain therapies for specific pain patients faster than the current trial-and-error method. Other doctors don't think imaging is going to help much, because pain is so complicated. After all, we know where in the brain we see, but where in the brain is beauty?
