This has been going on for a few weeks - my tongue feels, well, not numb but not right either. A similar sensation to when you burn it on hot liquids, very sensitive to textures like scratchy toast too.
Like I said it started a few weeks ago. It then went away week before last which was coincidentally the week I was off the contraceptive pill (Levest) and then started again the day after I restarted the pill. I was starting to get scared that I'd suddenly developed an allergy to fish as I also got an itchy throat that night - I've attributed the itchy throat to hayfever though, it seems most likely and went away when I took a hafever tablet. (The toungue thing stayed.)
I'm going to call the doctor next week but as it's the long weekend I thought I'd ask here if anyone had any ideas about what this could be??
