Onco says Herceptin does not cause side effects even though the manufacturers of herceptin says it can. So, the peripheral neuropathy, sore throat, itchy rash, ridged and cracked nails, breathlessness...
@Zoffiel Funny enough, the knees don’t itch now. My arm and neck have little itchy welts on them and my scalp also has little bumps which itch and the lavender eases it. Not really concerned about the knee and leg bumps unless they irritate me. I will try some anti fungal cream on one knee just to check out whether it gets rid of the bumps. I like doing unscientific trials. @kmakm I am ER- so all okay to put on skin.
