Anyone using Christopher’s comfrey ointment and/or complete tissue and bone?

I had a Navicular fusion surgery back in July and recently began partial weight bearing. I have a lot of pain/sweeping after walking a few steps and someone suggested I use the ointment.

I got the ointment and the complete tissue and bone and I am wondering if I can use them both? What have your experiences been with either one or both of the products? Thank you!
