A Question for those that have been there, done that

Brianna is down in Ga visiting me parents, and she let me know last night that she hears "raindrops" in her right ear. The left side isn't doing this. She can still hear, but has the raindrops as well. Any ideas on what this is and how to fix it? I suggested that she charge up her battery, and we switched to her 2nd program (she has 3 programs that are the same). Could this be tinnitus? Anyone have an idea? Thank you!
