I noticed what I would call slight withdrawl symptoms any time I was weaned to the next lower dose. Hips, shoulders, wrists and forarms would react with very minor but noticeable pain that would start a couple of days after the prednisone dose change. And only last a day or so. The same kind of physiological response would take place when I would push the limits with physical exertion. I called those mini flares that would calm down. Diagnosed Feb. of this year and started @20mg. At 20 it was difficult emotionally and physically. I'm also very sensitive to any meds. Fatigue from sleep deprivation and yes lightheadedness with mild to moderate vertigo at times. Was down to 5mg in Sept when I experienced a real flare up that would't self correct. Was moved to 15mg for ten days and then to 10mg. I'm leary of any decrease for a while. It's like a security blanket for the winter months ahead because of how the cold weather affects my PMR. I want any control I can have on this PMR hiking trail. Was supposed to set up a telehealth appointment with my Doc a couple of weeks ago. Not sure where he wants to go next with me. Procastinating because I like the homeostasis of where I'm at now. I hope things improve for you and you find that balanced care plan that's friendlier with less intense side effects.
