My 10 year old has unexplainable foot pain
I'm reaching out because hopefully someone can give me some answers to my son.
He has foot pain on the bottom of his feet. It comes and goes and he has been experiencing it for at least 4 years.
Up until last month, this is how it used to go:
About 20 times a year he would experience the pain and 90% of the time it would be at night. I tracked it to try and find any correlation. I tracked what he ate to see if it were some sort of food allergy that caused it. No correlation. I tracked it to activities, and not really any correlation. The pain would either start in the early evening, or in the middle of the night. Sometimes it would be bad enough that he was crying and we gave him medicine and it went away. Sometimes it was the left foot, sometimes the right, sometimes both. We thought it might have to do with his activities like running, but we also noticed the pain would sometimes occur during the day when he had some other illness. So he would be in bed all day because he was sick, and also experience the pain in his feet.
My son plays baseball and we noticed sometimes after playing baseball he would have the pain. We thought maybe it was the running. However, he then started playing basketball and he had practice/games 3-4 times a week with much more running and jumping than he did with baseball. Not really any foot pain during basketball season.
We've been to his doctor over and over. We've had xrays, blood work, and now an MRI on one foot. Nothing is showing up. We saw a podiatrist 2 years ago and he didn't have any explanation examining the foot. We will now see another podiatrist because we just finished the MRI so we need to find out what to do next.
Starting last month the foot pain has been much worse and it is now lasting for multiple days straight. Before, it used to only occur at night and the medicine would help and he would be fine in the morning. As of today he has had constant pain for the past 6 days. Several of those days I had him basically off his feet for nearly the entire day. The pain will get reduced, to barely anything, but then at night it will increase and stay increased over night.
He is playing baseball right now. He does wear cleats, but we've had him stop wearing the cleats and he still has the pain. He also does very little running in baseball for the past 2 weeks.
Our next step is to see a rheumatologist. However, we have to wait for a referral and I don't know how long that will take.
I'm desperate for advice for my son. Please let me know if you have any suggestions.
Thanks in advance.
Edit to add: The pain is mostly on the ball of his foot and less on the heel.
