Erbitux side effect

My dad had his appointment Tuesday (9/15/09) and learned that one of his tumors (the larger one) grew from 3.6 to 4.6.  I guess its good news since dad has not been given his Erbitux cocktail for two months now. 

The doctor stopped his treatment because of the swelling of the feet and the cracked toe nails.  He wanted to give his a body a rest.  Well, my dads feet are still bad and the doctor wants to hold off chemo for another month.

His doctor told him he has never experienced with any of his patients and told my dad he plans on talking to doctors at UCLA and plans to call the manufacture.

Has anyone had this kind of trouble with Erbitux? 

My husband finished his Erbitux about 1 month ago and is having swelling of the feet/ankles/lower legs.  The doctor didn't think it was related to the Erbitux but he has never had anthing like this happen before and Erbitux side effects info states that rare cases of leg/foot swelling have occurred.  They checked and his potassiuim and protein were low so started some supplements and gave him water pills.  The also did some tests yesterday to make sure his heart was not damaged.  We are waiting for those test results.  Let me know if you hear any more info on this.
