My rash is almost completely gone after I switched to using a hydrocortisone cream on it.  I guess it is not related to the Avastin at all.  I wish I knew what had caused it though.  Then tonight I went to the grocery store and had to reach up to get something off of the top shelf and on the way down I scraped my arm on something sharp on the corner of the shelf and gave myself a nice long gash on my arm in the same exact place as my rash.  My arm looks terrible right now!
