Linders, can you tell us a little more, like how you got the fractures in your spine. Some offices are really slow, the busy ones, I guess. You might ask your doctor to give you a copy of the referral and process it yourself. Call the referred doctor and send them the referral. Lab work and dexa with TBS scan will give you a better idea of how to proceed. If you are on Medicare you might not need a referral to see an endocrinologist or spine specialist.
You already understand the need to have those fractures assessed (because of pain?), but there is some advantage in ASAP as often vertebral fractures aren't stable.
Supplements are usually not sufficient with osteoporosis.
You might call the office and ask the staff what the status is of your referral. If you know the doctor's name you might call that office and ask what has been received.
The wait time to see an endocrinologist is around 4 months where I live. You can almost always get in sooner by calling that endocrine office and asking for cancellations.
What is your research telling you?
