I could really use some help. My 8 year old son went to bed fine and woke up with sever knee pain. In two days he had pain his other knee too. He could barely put weight on either (but not swelling). He was walking with knees bent. We went to the doctor and they did a variety of tests. While we waited for the tests my son ended up in a wheel chair as he could not put any weight on the knees or walk at all. The tests showed nothing... no Lyme disease, no strep, everything was negative. My son had strep a few months prior, so the doctor advised it was probably that. They treated him with antibiotics. He improved each day and after 4 days, was almost back to normal. We also took him to a rheumatologist, but they also could not make heads or tails of this. They mentioned his thigh muscles were a bit weak. We took him for PT for 6 months. It seemed all was well.

Last week he woke up with severe knee pain again. We took him to the doctors. They checked for strep again and it was negative. We treated him with an antibiotic immediately, as we did not want this to spread to his other knee. In a couple days he improved and seems to be back to normal.

We have not been able to get a definitive answer from the doctors. We want to be sure we're being as proactive as possible in treatment to, hopefully, stop this from coming back.

If anyone has a smilar experience or things that should be considered for research, any insight would be appreciated.

Thank you,

  • My sister growing up used to get very bad "growing pains" in her knees (she'd cry with it at times). The pain used to often come and go.. often lasting a few days or so. She had this issue on and off for years (at one point she may of had the severe pain for several months at a time). Your post made me think of my sister. This may be your sons issue. It's also called Osgood-Schlatter disease http://orthopedics.about.com/cs/pediatricsurgery/g/osd.htm

However, give the improvement our son experiences with an antibiotic, we don't think that's the issue in his case. Not knowing the cause is very scary. Again, thank you. We value the input and ask anyone that might be able to help to respond.

  • The same thing is happening to me, but I don't think I would necessarily call myself a child. I'm 15 and yesterday I woke up with sudden knee pain. It took me several severely painful tries just to get out of bed. I cannot bend my knee, or straighten it without pain. There is one sweet spot where the pain is not as bad, but it is still very painful. I had no prier trauma! If anyone knows what this is please help! :(

Wondering if you ever found out the cause.
