Has your wife considered that her symptoms are PPD (https://ppdassociation.org/diagnosis), i.e. have a psychological cause which can be unconscious?

I had been suffering from unspecific aches, extreme tiredness, insomnia, sore throats, and other non-specific symptoms for the past 8 months. I had to take months of medical leave and went through 10+ doctors, accumulating negative tests and inconsistent diagnoses as I went along. Then, despairing, I read The Mindbody Prescription by Dr. Sarno and realized that my symptoms were due to repressed unconscious emotions. Since starting a free online recovery program a couple of months ago, I've gotten 80% better and I'm planning to resume work in a couple of weeks.

I know this sounds just like more quackery, but I promise you it isn't. There's more and more peer-reviewed research supporting the theory behind PPD, and the track record of long-term recovered patients speaks for itself. Feel free to email me at me [at] bobmichael [dot] io if you or your wife would like to chat more about this.
