My big toe is starting to turn inward and cross over on top of the second toe. is there anything to do for this?

See the podiatrist: Sounds like a bunion and hammertoe. The best way to evaluate it is by having it examined and an xray taken. Options can range from conservative to surgical depending on the severity of the deformity, the degree of discomfort, the impact on your function and pain.

Bunion: If it doesn't hurt surgery is not required. There are many devices that you would put in between the 1st and 2nd toes to spread them apart. This is a temporary solution. Orthotics can help slow down the process of the increasing bunion ( big toe over the 2nd) by correcting underline cause. Surgery is the only permanent solution. Please see a podiatrist to evaluate for your needs.
