occasionally (last night and mildly right now) I get these weird symptoms. tongue feels burnt (like from hot pizza or tea) and swollen. lips can be itchy. But the predominant symptom is a fine line between aching/numbness is my cheeks around the area of my cheek bone. I thought it must be food but someone told me it could be washing liquid or washing up liquid etc. Its quite distressing so any advice would be gratefully recieved
