, as a steroid user, I can also tell you my experiences taking it for a flare. While it's true that steroids can cause really uncomfortable side effects, you won't necessarily have them, or won't have the same ones every time.
I take oral prednisone rather than the IV because I respond well to it and it's easier than having to drive 15 miles to the closest infusion center. It takes three weeks to go from the highest doses (I start with 80 mg for three days and titrate down 10 mg every three days thereafter) to weaning off it completely.
I've taken steroids four times during the past 20 years and experienced quick, dramatic relief from flare symptoms during the initial highest doses each time.
Side effects started during the titrated doses that followed that. The very first round was the worst: anger and an aggressive outburst, an itchy skin rash, ravenous appetite and weight gain, fluid retention, facial swelling (called "moon face"😉, head zaps, a feeling of being drunk, excessive and foul-smelling scalp sebum (oil) that could only be controlled with T-gel shampoo, among other strange things.
But later steroid courses were not as severe. One course caused absolutely no side effects at all and stopped the symptoms in their tracks.
My latest experience in 2018 produced a painful return of muscle spasticity and other symptoms during the lower doses. Weeks after finishing, though, I did physical therapy and all my symptoms stabilized. It's well known that there can have a rebound effect while weaning off treatment and for weeks thereafter, until our symptoms settle and we can see what is permanent.
These are just some of the effects steroids can cause. But you can't know how well you'll tolerate them until you try it.
Hope my experience gives you some idea of what it's like. Others will report an entirely different experience. The effects are unique to each one of us. --Kim
