i think the medication route is your best option from what ive read it seems the baking soda is good to nutrilize and to pass through blockages but not sure any prolonged use would be benefitial. this sour crop is a long hard slog of a journey! if theres a fungal infection then fungal meds are needed . i had a time of getting thrush myself which kept reocuring (sorry for over sharing!) my point however is the doctor prescribed a six month course of meds. so it seems long term treatment for these types of infection are sometimes needed. my advice would be not to discontinue use of meds when you see improvements but keep the meds going until shes well and truley clear of infection. id say a good week after she appears recovered. just my opinion for what its worth x
