The flu shot was administered at approximately 9:50 am on 10/1/08, this was 10 minutes AFTER providing the doctor with a urine sample (9:40 am) for patient's annual preventative examination.  No blood was present in this urine sample.  At approximately 1:30 pm on 10/1/2008, there was blood visible in patient's urine.  I called Dr's office to have them make sure they test for a bladder infection because I saw blood in her urine.  At 5:15 pm on 10/1/2008 after her nap, there was still blood in patient's urine and at this time she was complaining of pain in her abdominal area and lower back area.  We then went to hospital at 5:30 pm on 10/1/2008 where the hospital took her temperature (low grade fever around 99), did a urine sample, and an ultrasound.  Patient vomited around 10:00 pm while at the emergency room and on the way out of the emergency room.  The emergency room physician did not know what was wrong so he released patient when he felt comfortable that her blood pressure had come down.  He instructed us to take her to Dr. the next morning.  The last time I "visibly" saw blood in patient's urine was at approximately 8:00 pm on 10/1/2008.  The morning of 10/2/2008 I took patient back to Dr. where they did another urine sample.  Since the night before, I had not seen any more blood in her urine; however, the urine sample still showed signs of blood.  Dr. was not able to identify why there was blood in patient's urine.  Dr. scheduled us to go to another hospital to see Dr. in the Pediatric Nephrology department.  Our appointment was on 10/3/2008.  Patient gave a urine sample which, when tested, still had blood present (although the blood was NOT visible to the eye.)  Dr. examined patient and asked us questions, trying to rule out kidney diseases and a bladder infection (FYI, patient NEVER experienced pain while urinating).  Dr. did not know what the cause was so he ordered blood work that was done at that visit on 10/3/2008.  Dr's office called me and said they wanted another blood panel done because when they took the blood panel on 10/3, patient was a bit dehydrated.  On 10/14/2008, we went to the Lab and had the blood draw done.  When we saw Dr. at patient's 10/29/2008 follow up visit, she had an ultra sound and gave a urine sample.  In the visit Dr. said her urine was normal (no blood), the left kidney was a little larger than the right but that may be normal for her, and her blood work from 10/14 was normal.  Dr. did ask for more blood work and for patient to come back for a follow up visit in February (she goes back on 2/25/2009).  I called to find out the blood work results on 10/29 and the nurse told me everything was normal and Dr. would have called me if something was wrong.  My husband and I feel she had a reaction to the flu shot; however, no one will confirm or even consider this.  Patient was well at the time of the flu shot on 10/1/2008 and there was no blood in her urine at 9:50 am.  Then just a few hours later at 1:30 pm there was blood visible in her urine which was no longer visible after 8:00 pm that night; she also vomited at the emergency room around 10:00 pm; and she had a low grade fever at the emergency room.  Patient did come down with a flu bug on 9/12/2008 at 8:00 pm and vomited off and on from 9/12 through 9/15.  However, she had fully recovered and was well the day of the flu shot, 10/1/2008.
