Hi I have a problem with my mouth whereby the inside of my lips feel rough and like I could bite the skin off. The doctor didnt suspect anything sinister but it's been happening on and off for the past 8 weeks or so! I've changed my toothpaste and in between times brushed and rinsed with bicarbonate of soda and it seemed to heal up but now I'm using the new toothpaste it's feeling lumpy again. I'm getting myself into a bit of a state so would really appreciate the voice of reason here to what it could potentially be or more importantly what it's not! Thank you.
