Hi, I have GI problem, twisting-like, almost like belly button is pulling back in GI pain that sometimes starts with back pain and radiates up to my chest area, sometimes I feel like something big is squeezing through my bowels & sometimes I feel heart discomfort, palpitations and like mini pain shockwaves. I don't think I have a congenital heart problem though, this issues started in my early teen years, I'm 21 now.
