I’ve had one shot, no side effects. My condition has improved and my stress fx have healed. I am also using teriparatide (Forteo) by daily injection. I’ve had 6 stress fx in 2.5 years from my knee down and including my foot. I’m thankful to be healed and fully ambulatory. My Dexa scores are not that bad but the calculation should be different for 65 and over IMHO. An article I read from 2021 stated that of the elderly group with SF 67% had only osteopenia. I say go for it!
