it's hard to say- are you on other meds (including insulin)?- if not, perhaps the steroid caused it via bone metabolism- i'll presume you were on a Ca (/Vit D) supplement to prevent bone loss, which can happen on chronic steroids (especially for women- won't guess your age :))- what is NOT well known is that it's important to take Mg along with Ca- chronic high Ca/Mg ratio is associated with heart disease, as well as insulin resistance- so if you have any (family) history of osteoporosis, or any bone pain, i would ask the doc if any diagnostics warranted with the steroid/low Mg status- good luck and remember- if anyone starts to annoy you, just tell them you have sarcoidosis- they'll probably leave you alone then :)
