My 24 yr old daughter started taking Biaxin on Chrismas for sinusitis. On Saturday am, she woke up with excruciating abdominal pain that seemed to be worse on the left side, and would radiate to her back. we took her to the ER. They gave her dilaudid ( a heavy duty narcotic for pain) and that helped but didn't take it away. They took an ultrasound and found her ovaries to be normal. They they did a CT scan of her entire abdomen. They also did a urine test and CBC. All tests were fine. They gave her a 2nd dose of diauded, which again helped some, but she still had pain. Finally, after 5 hours, they gave her a big dose of anti-inflammatory and then the pain went away. They sent us home and said it was just some mysterious thing. Now I'm wondering if it could be the biaxin kd in Ohio
