Hi Sheila, they sound like questions for your rheumy or doctor.
I have been on and off prednisone for 4 1/2 years. I find I need 10mg to make a difference if not more but I know at this dose it will weaken my bones and teeth, affect my skin and organs and mess with my ability to fight infections.
I am very soon going to try and wean myself off it again. I have periodically done this but never seem to manage that long without it, 3 months max so far. But I figure coming off it at least gives my system a small break!!!
My rheumy feels I'm unusual and normally people can be controlled by biologicals methotrexate and anti inflammatories without the need of prednisone. If you're still not under control, maybe you need to talk to your rheumy about upping your meds?
I think prednisone is suppose to be a short term measure while other meds kick in.
I am 51.
Hope this has helped but I think you need to talk to your doctor , we are all different in our needs afterall, golitho
