I have a had a sore numbness inside my mouth for about a week.  Inside my lips, my tongue,and the roof and sides of my mouth feel swollen and a little numb and are very sensitive to spices and acid, like diet coke.  There are random reddish spots, and it feels a little rough, but not bumpy.  Its pretty uncomfortable.
Hello! Welcome to Chat Doctor. You did not mention your age and your general health status. Coke and other acidic beverages are detrimental to the teeth. Please reduce your intake of these gas filled beverages. You did not mention if you used any new tooth brush, paste or mouth wash recently. Change it to regular one if you changed it. Burning can also be a cause in lichenplanus and other lesions, which has an autoimmune cause. Topical steroids are used for this. I advise you to see your dentist for a definitive diagnosis if this persists. Maintain a good oral hygiene. Use mild chlorhexidine gargle once daily for two weeks. If you are referring perimenopause discomfort, you must get this treated with your gynecologist. Regards.
