I have been on Tamoxifen for almost 4 years and often get ulcers and sore mouth. My mouth seems more sensitive now and any sharp food seems to scratch it and make it sore. Mouth wash can help.
I am sorry to hear you are going through this and I am sure some of our users will be along shortly to offer their support and experience.
In the meantime you could give our support line a call at 0808 800 6000 who will be able to talk to you about the side effects of Tamoxifen and also offer a supportive ear.
