Marilyn,
My mom was told about the cracking/itching of hands and feet. She started using utter balm, the one with the cows all over the bottle (this brand recommended by doctor) before she did the chemo. She did not get that sympton. Give it a try!!
My mom is now finished with her radiation and chemo. Did really well. Only about 4 times did she have to take a nausea pill. She lost about 10 lbs but they think that was from the surgery. The doctors are now discussing if any further chemo will be needed at this time.
Keep up that great attitude of yours. That is 95% of the battle. I wish you well and will pray for you.
Sue
