Heel neuritis doctor did alcohol injection with ultrasound is it a scam?

This episode actually comes from a question I got during the live question and answer period at the end of a talk I was giving at the International Foot and Ankle Foundation meeting in Hawaii.

The question was about one of the conditions that can often be misdiagnosed as plantar fasciitis, and that's a condition called medial calcaneal neuritis. 

With this condition a nerve on the inside of the heel becomes inflamed and painful. 

In short, the patient had alcohol injection under ultrasound guidance by another doctor, but the condition dod not get any better. 

The question from the doctor in the audience was basically asking me what my opinion about that procedure using ultrasound.

Today on the Doc On The Run Podcast, we're talking about heel neuritis in a situation where a doctor did an alcohol injection with ultrasound and another doctor wanted to know if that was a scam.
