Hum, I see, very interesting. I think you should go to the hospital, ER, and have another ultrasound by a trained practitioner, because you have all the symptoms of gallstones, to the letter.
Please tell me what you are eating 8 hours, 6 hours, and 3 hours before each attach. If you can't remember, please keep a record and do another post with the info. Gall attacks are a result of diet, so what have you been eating before each attack?
