Advice please-skin rash and taxotere

[Ellie F]

Had second dose of taxotere and herceptin last week. After first dose I got a very itchy rash all over my neck. This eventually settled down but has left a brown discoloured mark. My onc was not concerned but it has now appeared again and is also on my cheeks!
Heard that skin rashes are common on taxotere, any suggestions about coping with it or meds to reduce it would be gratefully received as it's driving me MAD!

Many thanks
