Gardasil and intestinal pain

I can't believe that after months of searching for an answer to my daughter's health problems I may have found it! My daughter was a healthy, active happy child until recently. She is 17 and started experiencing joint, bone and muscle pain and swelling, unexplained rashes, migraines, tingling in her hands and feet and was diagnosed with neurocardiogenic synchrony (heart rate and bp out of synch) shortly after her first shot (she was 14).

We have been to a rheumatologist for the joint pains, they did blood work and there is a marker for some sort of auto immune disorder, but nothing specific.

I never connected the dots to the shots. In January of this year she started having severe diarrhea, stomach and intestinal pains. She has no energy, the most basic activities wear her out. We ended up at a gastroenterologist looking for a diagnosis (they thought it was Crohn's or lupus). All the tests have come back negative, they said she had gastritis and blew us off. She is on medicine for the intestinal pain, a prescription for an antacid for gastritis and an anti-inflammatory for the joint and bone pain.

She was a straight "A" student up to January and has had to finish her junior year at home. It has been a very stressful experience for all of us.
