I was just doing telemedicine visit with a runner who has a red, painful big toe joint. 

Gout is an accumulation of painful sharp crystals in the joint. 

Gout certainly can cause your big toe joint to become red, hot, swollen and painful.

But gout is only one of three different conditions that might cause big toe joint pain.

The pattern of redness around the big toe joint can help you decide which condition might be causing the problem if you are a runner.

Today on the Doc On The Run Podcast, we're talking about whether or not a painful red big toe joint means a runner has gout.
