<s>[INST] My two year old daughter has had intermittent knee pain. It has happened twice, a week and a half apart. She wakes in the morning and refuses to stand on her leg. She cries and complains of a boo boo. She goes the entire day. Motrin seems to improve a bit, as for her mood, but not her walking. The next morning, is like it mepnever happened. [/INST] Hi...looks like a growth pain. This sort of pain is quite common in and around the weight bearing joints of the lower limbs especially when the kid is growing in length. Unless the kid has got a swelling or redness or small joint pins like finger joints or prolonged fever or the joint pains persisting for more than 6 weeks you need not worry. If any of the above symptoms develop, I suggest you consult your pediatrician.Regards - Dr. Sumanth </s>
