Hi there, I have CIDP since 2009 it was in remission until 2015 when it flared up, had solu medrol iv for 5 dys and this relieved all symtoms until 2022 August when I experienced pain in my left upper legs initially going across to the right hand side. I have lost complete muscle tone in my left arm and have 60% in my right arm. I have been on 3 x solu medrol for 5 dys over a period of 4 months with no long term improvement. I am trying to motivate my medical aid to pay for the polygam which will also be over 5 dys. I am putting a lot of faith that this will give me a longer period without pain. I am very weak and have had a lot of side affects from the cortisone. At present I have not taken cortisone for 6 weeks. What I don't understand is why it has suddenly been so aggressive and progressing so fast......very scarey!!
