I have done it, but asking your GI is the best way to find out what's best. I did cortifoam with a canasa... not exactly what you're thinking about, but similar.
It didn't help me a ton unfortunately. I guess when things are bad throughout, treating a small part didn't do as much as I wished it would. In your case, it may help. Fingers crossed!
