You don't ice the bare skin. You have some thin towel or flannel between the ice pack and the skin. Ice turns down the nerves which are overfiring.
Heat make it worse as a rule. You don't leave the ice on long...too long and it impairs the circulation. Just enough cold to quiet the nerve.
I read the other thread, and it seems like you figured it all out?
If you do cranberry, don't do the juice. Buy the concentrated capsules. They don't have sugar in them.
