Ugh! I feel your pain. I've been having sinus issues too. I don't know that herceptin is the culprit in my case though. About 1 1/2 yrs ago I had a virus that turned into sinus infection. I don't think it cleared 100% after antibiotics. Subsequent colds turned into sinus infections too.... the last one in March I finally went to an ENT & did 3 weeks of antibiotics which got me over the infection. But CT scan showed lots of inflammation in all sinus areas & the ENT said that would not resolve with antibiotics and would case same problems in future. He said the best option for me was sinus surgery to "clean things out" & get rid of the inflamed areas that are causing blocking. I opted not to do that but on PET scan in July the sinus inflammation was still showing up. I'm dreading getting more flu/sinus infections this winter and having to face the surgery for relief. Sorry I don't have a good suggestion for you, just want to tell who what's happening to me & see if it's similar. Has your doc talked about surgery?
