Story time: when I was TDY to Al Dhafra, the U-2 pilots could go in to Abu Dhabi and get massages with an American chiropractor. Apparently, the Emir was in Minnesota a few years earlier, used their services, and asked them to set up shop in Abu Dhabi because he was impressed.
I head downtown the day after a flight, and during my consultation with the American doc, I discussed my neck issues, explained that I had almost no feeling in my 4th and 5th finger in my right hand for the past 2 years, and he took x-rays. Finally, I go back for my 1 hour massage with one of the four masseuses. All four of them were from China, spoke almost no English, and apparently were pretty well trained.
After about 10 minutes of her working on my back and neck, she has me turn over, and in broken English asks which fingers are numb. She proceeds to work my chest, pectoral and arm pretty hard. After about 15 minutes, she sees the tears working their way out of my eyes and in more broken English says "too hard?"
"No! Keep going!"
When she was done, I felt like my chest and right arm had been turned in to ground meat. But it felt great.
About an hour later, on the drive back to Al Dhafra, the feeling in my fingers came back. And it remained for many years. I could hardly believe it.
That experience made me a believer in massage therapy and chiropractors.
