I got a charlie horse on my feet like on the first joint that bends the most when you walk. i don't know if its damaged, but when i bend my toes forward, i only see 2 joint balls instead of 4.

Charlie horse: It is unlikely that a charlie horse would damage the big toe joint. However , a podiatrist can take x rays and examine you to make sure all is ok. Good luck !

Exam: It wouldn't be uncommon for an adult to haves some arthritis in those joints, but not a 16yo. You should see a podiatrist for an evaluation. You might have problems with the growth plates, biomechanical issues or even something like juvenile rheumatoid arthritis. No need to be alarmed at this point but get it checked, just in case.

First joint : You need an x-ray to evaluate that joint what your calling a charlie hourse could be limited range of motion in the big toe joint see a podiatrist there are many effective treatments.
