On 25th September 2019 01:45, the patient received the 1st dose of Fluarix Quadrivalent 2019-2020 season (intramuscular). On 26th September 2019, 1 days after receiving Fluarix Quadrivalent 2019-2020 season, the patient experienced skin discoloration. On an unknown date, the patient experienced cellulitis (serious criteria GSK medically significant), elbow bursitis, swelling, pain, headache, sleeplessness, movements reduced and numbness of extremities. The patient was treated with ibuprofen and steroids nos (Steroid Injection). On an unknown date, the outcome of the cellulitis, movements reduced and numbness of extremities were not recovered/not resolved and the outcome of the elbow bursitis was recovering/resolving and the outcome of the swelling, pain, skin discoloration and sleeplessness were unknown and the outcome of the headache was recovered/resolved.   It was unknown if the reporter considered the cellulitis, elbow bursitis, swelling, pain, skin discoloration, headache, sleeplessness, movements reduced and numbness of extremities to be related to Fluarix Quadrivalent 2019-2020 season.  Additional details were provided as follows: The patient's mother reported that her son received the Fluarix Quadrivalent 2019-2020 vaccine on an unknown arm and within 24 hours, he experienced a ball at the tip of his elbow which she claims was swollen. He received the vaccine at 1:45 PM and he had a headache that came on early that lasted a few days. She called the ball on his elbow elbow bursitis and it caused him so much pain that he said that he needed a pain killer but he did not typically take medications so he took a lot of Ibuprofen and he was up all night and could not sleep. The following day he started to experience swelling down through his lower hand and the hand was turning purple. The patient went to the urgent care and they diagnosed him with cellulitis. They administered a steroid injection on 28th September 2019, that reduced the swelling on Saturday night. The injection also helped with the pain but the swelling took longer to resolve on his elbow. The ball on his elbow has gotten smaller but it is still present and moving around.  The patient's elbow cellulitis was still not resolved and he could not lift weights for the past 5 weeks.  The patient claimed that this was due to the stress from his tricep tendon that he could not extend and workout. The patient could not extend his arm.  The patient was also experiencing two areas of numbness in his hand and up and down his thumb and across the lower half of a finger or two fingers and across the base of the finger. The mother could not confirm which arm her son received the vaccination on or what side of the body his side effects are affecting. The reporter consented to follow up.
