You poor thing! Potty mouth when in excruciating pain is unrelated to age or circumstance so go for it ! There is always bisphosphonates for osteoporosis instead of Prolia but be cautioned to stay upright for at least half an hour after taking them - I’d recommend an hour walk. Also make sure you have a thorough dental overhaul before commencing them as serious dental is out eg extractions , root canals as they stay in your system unlike Prolia. I was on bisphosphonates onand Off fleetingly a few years back but am now o Prolia which seems ok. Admit to being very worried at the outset by Prolia ( and Letrozole) about side effects but been ok on it .
