1. Herceptin and heart murmur 2. Nails breaking

[grateful2015]

Hi. First time joining you. Feeling anxious. Finished 12 wks Taxol/Herceptin in April. Dr. heard heart murmur this week even though 4 Echo's normal. Heard heart issues reversible but don't know how that happens. 2. Someone posted re nails breaking/peeling. My fingernails started breaking in Dec. 2015. PA suggested I take Biotin which I started 12/22. Seems to be helping a bit.
