Is there a regimen of regular high dose steroid injections like once a week or once a month to check the progression of the disease?
Other than the use of steroids for acute relapses, usually for 3-5 days, there is a treatment protocol called "pulse steroids." With pulse steroids, the MS patient receives 1-day monthly steroid treatments to keep the MS in check. Usually this is used when a patient has more active MS and/or has had more frequent relapses.
For a few years of my MS I took a week of steriods once a year. It worked well for me. About 5 years in my doc swtched me to 3 to 5 days each month otherwise known as Pulse steriods that Lisa mentioned. That menthod did not work as well for me. Yes my energy/stamina and strength improved but I found myself "craving" the next treatment every 3 weeks. I have also heard that some people can't make a move on a daily basis without their steroids (scary). I haven't even mentioned the weight gain that comes with steroids (food never tasted so good). So consider carefully. I have since only used steriods when absolutely needed. Good Luck
