mouth sores & hand/foot syndrome-am on Xeloda

What you ladies do for mouth sores. Also, those on Xeloda, what do you do for hand/foot syndrome. Xeloda is causing me side effects, I had never gotten with other chemos. Need help.
Onc. put me on Celebrex and Vitamin B6 for hand/food syndrome. I also heard about Udder Creme. I have been using, but still bottom of feet and hands red,painful and hot. I have been gargling salt water, no help. Today, I went to drug store and bought over the counter- Orabase, which has Benzocaine to numb the pain. It helps, but wears off easily. Any new ideas? Please post. Thanks.
