I have Raynauds and Scleroderma and just recently have been troubled by altered sensation in my mouth. It feels as if I have scalded my mouth (which I haven't) - tongue and mouth are sore and I haven't much sense of taste. I have been having reflux problems lately where my usual meds are not controlling the acid any more and my gp has now taken me off Omeprazole and put me on Esomeprazole. This seems to have controlled the indigestion pain but I'm awaiting an endoscopy to see quite what is happening. Has anyone else suffered from anything similar?
