Can I put a "problem" in the freezer spell, effecting my loved one

Last night I did a freezer spell on someone who was bothering me physically as well as mentally, within 24 hours it worked instantly. It might be one of the best spell I've ever done.

Now coming to the main topic, my grandmother is having very high blood pressure since 2 weeks. (yes she is under medical treatment). The freezer spell I did last night was so instant that it made me think can I put my grandmother's high bp problem in the freezer spell. Will it stop this critical situation. Or is it a bad idea
