No. Not sure it would work. I tried all kinds of anti inflammatories, ice and stretching and nothing worked.
The pain is there because the tendon is inflamed. It is inflamed because I ran too much and it was stretching and retracting continually.
I've had 2 cortisone shots in that foot. First one helped, 2nd one got it. BUT - the podiatrist told me that once it happens, you are prone to it and that I should do another type of cardio because running was going to make it return, eventually. He was right.
Cortisone shots are not good for you, long term, as they weaken the tendons and ligaments. Awesome short term, though.
