Okay...I'm just gonna say it...lots of runners get funky toenails. Runners get bruised toenails, black toenails. 

But the worst thing  is when the nail lifts up off the nail bed and you get fungal filaments that cause athlete's foot underneath the toenail. Then you get toenail fungus or onychomycosis.

If your doctor recommends oral antifungal medications, you may get worried about the side-effects of the medication.

Just today I saw a runner with toenail fungus. He wants it gone!

So I was talking to his primary care doctor about the potential of modifying the normal routine for oral medication for him so that he could reduce his concern for having liver problems as a consequence of taking this medication. 

Today on the Doc on the Run podcast, we're talking about a couple of options you have if you are thinking about taking oral medications for toenail fungus.
