Dear Judy,
I think every person has different side effects. I have insomnia, body aches, constant runny nose, headaches, but no problems with nails or cuticles. I have been on Herceptin almsot a yr, this is my 2nd episode of BC, first in 1995, had lumpectamy and radiation. This was much more aggressive, Stage IV metastatic with tumor on spine, have had radiation to spine, lungs, now in holding pattern. Due for CT in a couple of weeks. At this point no spread to lungs or liver but tumor not decreasing either. Keep in touch and let me know how you are progressing. I hope you continue to do well and some day there will be a cure for this dread disease.
Hugs,
