Hi - I recently started a drug called letrozole (changed from tamoxifen) and am on dasatinib. I was so ill after the change of drug I halved the dose of letrozole and felt a bit better. However I am having terrible pain in my upper stomach and back, and occasionally jaw. I often burp a lot too. The general practitioner has given me Gaviscon but it isn't really helping. I think I may have some sort of stomach ulcer. I am planning to phone my haematologist but wondered if there is any effective ppi or even antacid that I would be able to get. The pain is really getting me down.
I've searched the forum but can't find anything closely related.
