Pam,
You might try cancercare for help with travel. I know a a few people that have received travel funds from them.

You might also check the links listed under the Resources tab here on HER2support. There are several foundations and organizations that might be beneficial to you.
I hope the discomfort subsides for you very soon and your next step leads to success.
