@annar the oral bisphosphonates can be tough on the esophagus.

Please let us know if this turns out to be part of the short term "acute phase reaction" that is common with the first infusion. I hope so! It tends to happen only with the first infusion, according to mu doctors. I had fever, fluish symptoms and GI stuff.

I posted elsewhere about adjustments to dosing, duration of infusion, timing and so on.
