hi nanmac!
physicians really & ideally would not like for their patients to be on prednisone for a very lengthy amountof time. mostly because it will, in long term, rob your stores of calcium in bones & also screw with your endocrine system (your own NATURAL steroid your body makes).
but the kicker is we often will need to do a few months on them, some longer.
most important thing you can do is report to your doc if & when you feel like something's wrong, or the side effects are getting too bothersome.
i get muscle spasms. twitches that go on for like 10 minutes ata time. in my hands, thighs, arms....i dunno, i feel they're benign. but check it out.
take care nan...write back soon. {{{{{{{{{{{{hugs}}}}}}}}}}}
