Herceptin reaction

[Maggie]

Hi ladies,
I had my 3rd Herceptin treatment last Wednesday. I read hear a couple of days ago that you could have a runny nose from Herceptin and I do have that.
I have another question! In the last few days, and also several weeks ago, I have had tiny dots like a pimple, on the edge of my lips. They are just discolored, though not sticking out like a pimple. After realizing I had them before, I'm wondering if this could be a reaction from Herceptin, too.
Has anyone had this happen to them? It really looks like I smeared my lipstick. Not too attrictive looking either, but that's OK!

Thanks, for any input on this.

Maggie
