Hi dawn, unfortunately my gp who is amazing is on holidays so yes this young dr was my only choice at the time when I became defensive about stopping tamoxifen he soon backed of and did say ring the onco. My own dr asks me in depth about bc progress he learns from us . I've met a couple of Doosey nurses looking after me too, I've just always kept my humour..Surprisingly I remember my onco asking in depth questions before tamoxifen started ,about any gastric issues, and also very recently at Peter mac by a very young registra, perhaps if you have a underlying issue it agravates it along with everything else, joy oh joy. Mind you the nexium is working a treat and only 2tablets so far. Thanks for your concern . Adean
