Hmmm. I am currently having those same symptoms, along with overwhelming tiredness. I have a call into my neuro, as I was also on a 28 day regimen of prednisone for what I thought was a MS flare up at the time. Steroids worked at the time, but have been finished over a week and now these symptoms. I was diagnosed with MS 19 months ago, MRI with lesions, and a spinal tap with bands confirmed MS, after 15 years of having other symptoms that would come and go.
I am so new to this whole MS thing, I'm not sure half the time if what I am feeling is related to MS, or just because I AM getting older, hop, jump and a skip from 60....
Sorry I could not answer your question.
