I think what has happened
in your case, is that your pain relief medication,
Oxycodone has had some issues
in side effects very similar to being hypo. I do wonder why you were on it in the first place?
I am wondering your question about Prednisone; if you took it years ago, and you noticed hair growth, are you losing hair now and considering taking it again to regrow your hair? If so, I would highly advise not to.
