I am 29 and have been dealing with hoarseness almost all my life, even before I was diagnosed with CF (I was diagnosed at 15). As you can imagine, I have tried a lot of things to make it go away, from chemicals to natural products and the only thing that really works is to rest my voice for a few days until it goes away. At one point I was seen by a throat doctor and he could see that I had polyps on my vocal cords, which makes me prone to losing my voiced easily. And then after many years I have come to realize the following: I am bilingual - I speak English and Portuguese - and I pretty much only get hoarse if I'm speaking Portuguese, but if I'm just speaking English I don't lose my voice for months on end. So I guess in this case it's got to do with the sounds of each language. Maybe not so much the medicines I take.I think having voice lessons is a great idea, and I think it can help. But maybe not when she is actually unable to speak, maybe it would be better if she waited until her voice comes back because her vocal cords need to rest.
