Osteoporosis

Good evening all
I hope this message finds you all in good sprit?

I have a question:

I have recently been told i have the start of osteoporosis. This was found after breaking my leg at the gym.
To improve this, i've been advised to take vitamin D everyday.

I have also been given,
Zoledronic Acid in form of a dip.
Here is my question
Has anyone had this?
If so, have you had any side effects?
If yes, what are they?

Thank you in advance for reading this message and hopefully answering any of the above question
