I have been diagnosed with Gillian Bare' due to a flu shot. I'm in therapy now. my right arm (not as affected, but hurts) The bone in my left arm where the shot was given is severally painful. i have swelling on my left side only.....my wrist, knee, leg and ankle. The Dr. prescribed predniosone (10 mg) but after reading the side affects, ( causing swelling and bone problems, also causing muscle aches). I already have these symptoms. He thought it would take the swelling and pain away, but it sounds like it would cause more of what I already have. I an 76 yrs. old, weigh 128, 5' 8", with little body mass. Should I take prednisone or not?
