There is nothing on my upper lip that is visible at least, but when I pinch the dimple part right in the middle of my lip it hurts very bad.  I dont even have to apply much pressure and it hurts seriously bad.  It has been like this for a couple weeks now... whats going on?
Thanks for your query, I have gone through your query. The pain could be because of any crack in the lips, or it can be because of neuroma within the lip or colitis granulomata or any cystic lesion within the lip, or it can be neuralgia. Consult your oral physician and get it diagnosed.  After diagnosing either you can take medicines like analgesics or other treatment like surgical removal of cyst or neuroma... I hope my answer will help you take care.
