Hi,
In the last month my son (5 year 9 months) started complaining pain in his knee with no swelling & no fever. We called the doctor but he said if there is no swelling and fever there is no problem, give him Morten. On next day night he got the fever & next morning we went to see the doctor.
Doctor told us, he dont have pain in his knee, he has it in hip. & told us to rush to the ER.
In the ER, after doing x-ray, MRI, ultrasound & blood test, doctor told us he has fluid in hip & may be infectious. Immediate they drew the fluid and after lab work it came out ve. So surgeon operated his hip.
After that he was in the hospital with antibiotic (vancomycin) for 3 weeks.
When we went first time, the SED RATE was 85 & after 3 weeks it came down to 26.
So infectious disease doctor told us to go home & told us to monitor the ESR.
But for last 10 days SED RATE is still 26. My son is doing good & he is not complaining any pain anywhere.
Doctor told me if SED RATE does not go down in the next week, he will ask us to admit to the hospital & he will start the same antibiotic treatment.
Can anyone suggest me what may be happening?

Thanks in advance,
Milind
