A 32-year-old member asked:

What are the symptoms of herpes/cold sores/canker sores on your lips/mouth?

Two different things: Cankers (recurrent aphthous ulcers) are an "auto-immune" type reaction to trauma/stress (such as biting your lip). They occur on the loose membranes of your lips, cheeks and floor of the mouth. Your dentist can treat with prednisone, laser or chemicals to cut pain. Cold sores are hsv. Abreva helps those some, but most need doc rx. Both go away without treatment in 10-14 days (pain only 3-5 days).

Possibly: If it started off as a clear fluid vescicle first and occurs typically in the same place repeatedly, it could by herpes. If not it could be apthae. These - aphthous ulcers -are typically on the mucosa caused by your immune system that attacks your own mucosal tissue. If these ulcers are large and occur frequently, steroid medications may be indicated. Consult with your dentist or physician.

A 33-year-old female asked:

Can canker sores - not cold sores - be popped? Can they appear on lip?

Not on lips: A canker sore is painful sore or sores inside your mouth -- on the tongue, soft palate (the back portion of the roof of your mouth), or inside your cheeks and not on the lips. The cause of canker sores is unknown. If it is on your lips it may be a cold sore so i would not recommend popping it.
