limp; hip pain/ right hip pain/ had tenderness in the right hip but not the left; right thigh, and hip pain/right thigh pain; Vomited; toxic synovitis of his right hip; inflammation; This is a spontaneous report from a contactable nurse (mother) from medical information team.   A 7 year-old male patient received bnt162b2 (BNT162B2), administered in deltoid right, administration date 03Nov2021 10:05 (Lot number: FK5127) at the age of 7 years as dose 1, 0.2 mL single for covid-19 immunisation. Medical history included eczema when he was a baby and innocent heart murmur. Concomitant medication included: FLU. Registered nurse said her 7-year-old son received the 1st dose of the Pfizer-BioNTech Covid-19 Vaccine orange cap presentation on 03Nov2021. Then on 09Nov2021, he started having right thigh, and right hip pain, and a limp. The patient also vomited. The patient was in the middle of a pandemic and it was his turn so he received vaccine. On 09Nov2021 the patient started having right thigh pain and a limp. The caller brought the patient to the regular doctor and she diagnosed him with toxic synovitis of his right hip. They did a urinary analysis, a CBC, and pelvic hip x-rays on the patient and that work up came back fine. The doctor recommended resting and ibuprofen if the patient needed it for pain. The patient didn't want to take the Ibuprofen because his pain was cut in half the next day. The caller thinks that the patient's hip was manipulated in the doctor's office but she is unsure because she was not there. Then the following day they were resting the patient's hip and he seemed better. On 19Nov2021 the patient started having a limp again and the pain was back, the pain was much less but the limp is ridiculous it looks like it should be off the chart pain. The patient rested and took Ibuprofen the next day. Even though the patient did not have severe pain the caller still gave him a couple of doses of Ibuprofen on 20Nov2021 and two doses on 21Nov2021. The caller figured the ibuprofen would help the patient with inflammation. The patient saw the Dr. on 22Nov2021 because he had the hip pain and a limp on 19Nov2021. On 20Nov2021 the hip pain and limp was there but resolved on the 21Nov2021. The patient saw the Pediatrician on 22Nov2021 and at the time he didn't have a limp or pain. But when the doctor manipulated the patient's left hip he didn't have any pain and when she manipulated the right hip he had pain. When the doctor manipulated the patient's hip she made him lie on his back, cross his legs, and push on his hip. Because of this event the doctor told the patient to not get the second dose which was scheduled today (24Nov2021). The earliest the patient could see the Orthopedic is on 01Dec2021. The patient hasn't had fever but on the way into the Drs. office he vomited once and it was a random thing. With the patient being 7 the caller doesn't know if this was related to the vaccine. The patient also said the meat didn't taste right but he ate it anyways so that could have been it. The patient has not vomited since. The caller clarifies that when the patient first got this pain he would point to his thigh saying it was there but then the doctor was able to locate the pain at his hip. The caller did the manipulation on the patient today and the patient had tenderness in the right hip but not the left, he is not complaining of the pain or limping. It isn't present now.
