Not good news, hope they find the problem with the port, i am on the Docetaxel also and the sore joints, tongue, mouth and runs seem to be common, as i have had all those, but am now severly constipated, so taking stuff to undo that, have you spoken to your breast nurse or surgeon about the weight loss? i have put on alot of weight, as i also have lypheodema from my 1st diagnoses, so fluid is always a problem.Like you i have ended up in emergency twice since starting treatment, they treid to get a port in, but mine would not work, so will have to put up with my herceptin for the next 17 rounds with constent jabs. How are you going with your appetite, i am always asking the lovely breast care nurses for advice when uncertain, they have been great, thinking of you with alot of hugs, Kerri
