Can heel raises make insertional Achilles Tendinitis worse?

I got a question on one of the Doc On The Run YouTube channel videos about insertional Achilles tendinitis.

Kevin asked:
 
“For a few weeks, I had insertional Achilles tendinitis. I have read that doing heel raises over a step could make the situation even worse. Some suggest doing it on barefoot in a flat zone. What do you think?”
