Mrcp symptoms and conditions

My husband was having gastrointestinal problems for about a week. The PA at his primary care physician's office prescribed Levaquin for 7 days. Blood taken ½ hr after Levaquin started showed liver levels to be a little high. By the 3rd or 4th day my husband was jaundiced. Blood taken on the 6th day revealed liver levels dramatically higher. He is still jaundiced and liver levels are still at the higher level. Had ERCP procedure, CT scan of abdomen and MRCP, but no conclusions other than stricture of bile duct and possibly pancreatic cancer, although a mass has not been seen on any film. Has this happened to anyone else on Levaquin? Doctors want to try ERCP again and if that does not work then the Whipple Procedure which is major surgery to remove a possible pancreatic cancer that they have not seen.

My significant other took Doxycylene, 100 mg, twice a day for two weeks to treat a swollen lymph node under his arm. During the treatment he experienced nausea, stomach pain, rash and cold sweats, nothing too bad. 3 days after the last dose everything got significantly worse. It started with sever chest pain, so bad we went to the emergency room thinking it was a heart attack or blood clot. They found nothing and discharged him. Over the next 3 weeks he started vomitting, diahrea and developed jaundice. Constant queeziness and chest pain. After numerous tests, ultra sounds, MRCP, the doctor has ruled out various hepatitas's and every other disease he could think of. He's also rulled out any kind of bile duct blockage after the MRCP. Its now been 7 weeks since all this started, my friend has dropped 40 lb's (190 down to 152) and still dropping. Our doctor (gastro interologist) has admitted he's stumped and is currently contacting a professor in Miami as a last hope. The only thing our doctor keeps comming back to is the Doxycyclene and that my friend may have had that one rare acute reaction. We're frazzled and don't know what to do next.
