The package insert told me more about it. I don't know if there was an insert in the last package, but I didn't find it.
Most people, the package says, find relief after ONE application. But the older you are, the longer it takes. So that explains why, partly anyway, I am not done yet. I may also be having a systemic reaction. Not sure of that yet. If so, I need a trip to the prednisone injection.
