I was started on 100mg Gabapentin for ferocious pain waking me up at night. My adult kids first noticed and brought to my attention that my breathing had become very “heavy”. I started paying attention and they were right. I’ve never had any lung issues, never a smoker, no second-hand smoke, etc. I dug out the pharmacy brochure and breathing issues are right there in the potential side effects. I went to the Mayo Clinic website and the PN Foundation website and began to follow their recommendations for using your brain to beat back the pain. It took constant attention and determination to make it succeed, but it has. Something that really helped was to remind myself often that I had my two children during the 70’s fad of “natural childbirth”, using the Lamaze breathing and mindfulness techniques successfully during long labor. A doctor told me the techniques were essentially self-hypnosis to divert your brain from the explosion of pain signals traveling up. If you research the current Pain Management Clinics, a big part of their programs is this brain “technique training”.
