HER2 Neu Positive 4 weeks of diarrhea and strong tissues

Hello There;

Does anyone has had the following as I am very worried.  I was spending four days in Vegas, not to long ago (Aug.3-7, 2014) celebrating my cousins 40th Birthday Trip.  I couldn't miss my chemo so my trip was shorter then everyone, which was okay as I feel living is whats important to me right now and I can not miss a single chemo treatment.  I want love to be the next person living to 40 and pass it too.

Anyway, the issue I am having is that I've had diarrhea going on 3 weeks now and I am losing too much weight fast.  I live in Bermuda and it seems in order to get something check you have to make noise for them to do  anything like go to the radio/or local news.  They tell me the insurance dictates to them what they can do from what they can't.  I told them no, this is my life and no insurance company is going to tell me what they think is right or wrong or what treatment I can have from what treatment I can't because it cost too much....They are mad as if its their family members they will get what ever they want I am sure.  As they are not the experts and they do not have any rights denying my care.

The only oncologist on the island has resigned and they have brought in a lady called Dr. Warner (who is from Jamaica) comes on the island for one (1) a week a month.  When I was in Beth Israel Hospital, under Dr. Come who was my oncologist and Dr. Glazor who was my  surgeon.  I still have pain in my back where is put a rod there.

The question is:

Has anyone with this type of cancer (HER2 Neu+ Stage 4) has had diarrhea for over 2 weeks and what did your doctore do?

Has anyone passed out these from their rectum area (see photo)? SORRY FOR THE GRAFIC...there is no bowl in the photo...the brown was in a sac like thing.

What kind of treatment you had for this type of cancer

(((((( PLEASE HELP ))))))
