Thorton it is nice to meet you and I'm so sorry to hear your sister is having such a bad time of it. When did she go thru her treatments and what chemo did she have?
I did get diagnosed with CHF in 07. At that time I was on Taxotere but it was my second diagnosis.
The first time I was diagnosed I had Adriamycin and my heart doc says that is exactly where I got CHF.
So I have been hospitalized a couple of times and it is an ongoing lousy problem. I have been put on Lasix and Potassium but I still continue to hold fluid which is not good.
Your sister needs to see a doctor if she hasn't already and get a check-up, maybe a test or two to see exactly what they are dealing with.
I see Nancy has given you many links for assistance but I will look for you too. If she is working she can apply for disability. Or as Nancy said she can apply for ssi to get some help.
I hope everything works out for her, let us know, will you?
