Symptom narrative

The same day of the shot my sons arm was extremely sore and he didn't want to move it at all. The next morning at 7:30 a.m. when he woke up he said his leg hurt him and pointed to his hip, he told me he didn't want to walk and asked me to carry him out of bed. He had a low-grade fever and I gave him Mortin. later that day he seemed to get a little bit better and was walking around. The next morning, he told me he could not walk and needed me to carry him. This time I could see a visible difference in his face, and I could tell he was feeling a lot of pain. He did not want to walk and sat in a chair for over an hour. I called the nurses line ( it was a Sunday so I could not speak to the pediatrician) they advised me to take him to ER since the shots were in his arm and not in his leg. When we got to ER he tries walking and was walking with a visible limp and walked very slow.

Lab data

His x-ray results came back good. Hid bloodwork was good as well. Nothing was of the charts, but his ultrasound picked up fluid in his hip. They ended up diagnosing him with transient synovitis. They originally wanted to give him antibiotics, but I said no. If his bloodwork is good why would I give him antibiotics?
