Hi Frogger, and thanks for your post.
Do you think your hoarse voice might be related to a side effect of the metered dose inhalers (MDI's) you're using? Or, is it possible you picked something up (infection-wise), while you were hospitalized? It is also entirely possible that this is just plain laryngitis - have you had an opportunity to discuss this with your doctor(s)?
I'm hopeful others in the community will respond to your inquiry. As you may be aware, we cannot provide medical advice or diagnostics over the internet (for your own safety). I did want to give you some ideas to think about and explore with your physician as you look to evaluate these current symptoms.
Wishing you well,
