Indigestion could be from too much stomach acid or too little and it's best to not medicate until you know which situation she is dealing with so that she gets the help she actually needs.
At this point, most anything could be irritating her throat. I would encourage you to try stopping some of those things (but if it's something she's using for detoxing, be sure to replace it with another detox routine), and see if it eases up.
Of course, we are all pulling for your daughter's healing!!! It's bad enough to deal with this as an adult, but I remember the agony of being a child with these infections, and that's even harder to deal with!
