No these tests are NOT fun and I would highly suggest using a pedi specific office to have them done. We had both our girls tested at COoks in FW and had good success. I have heard they are giving anestesia now but neither of my girls were able to have it.
Also if it is found check out www.deflux.com we had this for our oldest, she was a grade 4 on one side and a 5 on the other. She was having breakthrough infections even on the antibiotics. After the surgery she has been 100% normal, only 1-2 infections over the past five years.
Go into it knowing that anestesia changes your child until they come out of it. Some are cuddly and loving but more often they are thrashing and angry, it will pass in an hour or so, dont be alarmed.
If #1 has it, #2 jumps to a 50% chance of having it. We tested our second one much earlier because of sisters history. The younger they are and cant remember the testing, the better off they are imo.
Our oldest has a drs note on file at the school giving her permission to use the restroom whenever needed. Frequency and Urgency are still common for her and holding it greatly increases her chances of infection. Some teachers are understanding, others need the letter stating it is a chronic condition and will not go away next week. Following their two breaks a day will not work for my child.
Good luck and know this too shall pass!
