Hi, Louise,   Honestly, I'm not sure about the long-term impact of using steroids for three days a month, but if I were in your place, it's definitely something I'd ask about before starting the treatment. I know of one young woman who ended up having to have knee surgery when she was just in her 20's because she'd used the oral steroid dosepacks frequently over several years. I don't know if the treatment your doctor is talking about carries that risk or not. If you have diabetes, please talk with the doctor who treats you for diabetes too because steroids can cause an increase in blood sugar levels. For that reason, steroid treatments aren't an option for me.   Something else to discuss with your doctor, if you haven't already tried it is IV infusion of magnesium sulfate. For some people, it works as well as steroids with far fewer potential side effects.   Keep me posted? Teri
