I am currently on Dexamethasone to reduce brain swelling from the cyber knife radiation I had for my AVM. I have been on and off them since June 2016, but more recently I have been solidly on them for almost 3 months straight. I am noticing a lot of swelling and water retention all over my body like my face, neck, arms, stomach, back, and ears even. Does most of this go away when you stop taking the steroid? I’m worried at all the weight gain, its easily 25 lbs + I’m hoping its not permanent.
