The pain is probably caused by muscle weakness and nerve damage!
Ivig will stop the progression of nerve damage and allow healing if his body is under attack.. You can look up information on this site..
I took some pain meds initially, but personally am not a big fan…
I had severe back pain, as well as other probs.. I don’t understand why your
doctors are unsure of treatment!
If interested you can email me or any one of several others on this site for more info…
Good luck… Deanop
