I start burping as soon as I start exercising (especially stretching) or while I am getting a body massage, or when I am doing acupressure! Can you kindly explain the logic behind it? Note: I am dealing with SLE from 12 years, Fibromyalgia from 10 years and Sjogren's Syndrome from 5 years, and hence I generally feel pain and fatigue in my body. Burping after exercising/massage/acupressure relaxes my pain!
