Question
My 4 almost 5 yr old son will wake up crying with right knee pain.  That happens periodically.  Now he is complaining when he wakes up in the morning that his right knee hurts when he bends it. No swelling, not warm to touch and no fever. He doesn't want to walk on it.
Thanks

Answer
Hi, Jamie,

Most night time pains in joints can be evaluated extensively and nothing is found.  If it is only the right knee and it hurts in the morning consistently, then see your doctor.  He/she will examine things, perhaps do an xray if appropriate, and may do some blood studies.  

If it was just migratory pains in the legs at night, I probably wouldn't do anything, but specific pain in one place, with the symptoms persisting until the morning, warrants some evaluation by your doctor.

Good luck, Dr. Olson
