I think there is a connection. As I understand it (which isn't V much), people with thyroid conditions do often get osteo too, usually the thyroid condition being the underlying reason for the osteo. Don't panic too much, neither of these conditions are life threatening and both are treatable.
Wait until you get all your lab work finished and then you and your doctor can make some decisions re treatment. If you DO turn out to have a thyroid condition, you may be sent to a specialist.
You might also find it of some interest to check out the thyroid board right here on ''healthboards''.
A word of warning. If you're ever prescribed a bisphosphonate medication (Fosamax, Actonel, Boniva), among the oral ones, don't rush into filling the prescription. Do your own research first. It seems there are just too many problems and side affects with these meds for many people, so be wary
