oh my, sorry to hear that <img>
I had the same problem and I can tell, that it hurts like hell <img>
What a drag, that one of the attacks occured during a show! Now, that’s really professional: To contiue a show under these circumstances!
I had my gallbladder removed through laparoscopy and after about one week it was a part of the past and I didn’t have any problems from it, afterwards – a big progress, compared with those severe pain attacks before the surgery.
