Adding Ice or Heat to Dit Da Jow Applications?

This wrist pain article covers the application of heat to carpal tunnel, tendinosis, osteoarthritis, strains and sprains. Heat seems to help with pain relief and grip strength.

And another article advocates treating acute low back pain with heat and exercise, although beware that this one was funded by Procter & Gamble, who make more money off of their ThermaCare Heat Wrap than they would off of ice packs.

Has anyone tried adding a heat source to their topical Dit Da Jow applications?
In Chinese medicine, ice is not used for injuries because it supposedly pushes the injury deeper and can cause arthritis in the area years later.  Some herbalists even go by the motto that "blood follows heat."  But, most allopathic physical therapists and Western doctors often recommend ice for injuries.

Has anyone tried adding ice?  Has anyone tried both or alternating between heat and ice?

Just curious to learn if one or the other or both has been most effective in the experience of those using topical Jow.
