I'm 19 this year. Just a days ago, i began experiencing discomfort on the middle area of the upper lip, to be exact its the pointy part. It used to be soft, but now it somehow feels as if it has thickened and hardened. Since then the middle part has been less sensitive than the other areas. Never experienced this before and neither do i have any health problems. I've experienced dry lips before but none were like this, particularly at the middle area of the upper lips. Is it just another case of dry lips or it might be some kind of illness that has developed in my body? I have been taking lots of water lately but it doesn't seem to go away.I have not consulted a doctor for this but please let me know what you think it might be. Thanks.
