My 9 year old daughter has had knee pain for 4 weeks not. Her CRP and ESR were high: CRP=1.5, ESR=35. Indicating inflamation or infection according to her Dr. This knee pain began suddenly about 6 months ago. Was gone after a about 2 months and recently returned and has been present for 3 weeks now. She wakes up in pain and stays in pain all day and worse at bedtime. Her Dr. is baffled. X-rays of her knee and hips have been done with no indication of the cause. She is scheduled to have another bone scan done, which was already done 5 months ago and it was clear. She has a very high threshold for pain, due to many past bone fractures from sports injuries so I don t feel she is exagerating or making it up. She is depressed from being in pain 24/7, I give her 2 xtra strength tylenol at a time. She is tall for her age and also slightly over weight all though she has not gained any weight in a year according to her Dr. Do you have any suggestions to what might be causing this. This happened all of a sudden. No injury either time, she woke up with the pain.
Hither can be many possibilities which need to be investigated. Overweight, previous injuries, further examination and investigation to see if any other organ is inflamed will give an insight. She has this thing going on chronically, so you get opinion of a rheumatologist.
