-Do you know anything about giving these shots, by the way? I have been injecting in my upper thigh all this time but he, the doctor, would just pull down my panty and inject in my rear, upper hip (in the back)...-
Can't say I do know much about the B shots, but I do know a bit about IV ozone. I, like you have had it done a lot of years ago. The gurgling sound is the ozone out-gassing from the blood through the lungs once the blood is saturated, usually accompanied by an involuntary cough and little burning sensation in the lungs.
