Hey everyone, I was wondering if anyone here can shed some light on this issue. My tongue always seems to be smooth and red on the tip and going up towards the left and right sides. It always looks better in the morning before I've eaten anything and on some days looks much less noticable although I cant seem to connect it to anything. Sometimes a small patch within that area will get extra red and bit raw. It doesn't bother me physically but I guess it has to be a sign of something internal or a deficiency since its been like this for a while.
