I had ivig for five months and it did nothing for me. i am now doing plasmsphresis and it seems to be relieving some of the symptoms.
You need treatment.

Before being dx with CIDP I had calf and leg tightness. Also my toes are contracting and pulling downward.
You have been under a lot of stress lately and ? should go to MD and get started on treatment.
Good luck and know we all are pullking for you
