One device that gets around that difficulty is the aside. An aside is a short speech from a character that is spoken directly to the audience. The other actors on set can physically hear the words but as their characters, they pretend as if nothing was said. The audience understands that the speech was meant for them only. History of the Aside
Lip burning sensation may also result from different types of lip burns or even chapped lips. Certain types of neuropathy (nerve problems) may result in lip burning sensation, as the cranial nerves from the brain supply the lips. Symptoms may occur in the lips alone or any other area of the body that is supplied by a peripheral nerve. Lip burning sensation may be the only symptom experienced, it may start as a tingling (paresthesia) and change to numbness, or there may be a combination of symptoms. Burns from heat, cold, chemicals and sun may also cause a lip burning sensation.
Dehydration: A Main Cause of Chapped Lips. The most common lip problem faced by many is dry and chapped lips. Your lips are naturally coated with an oily layer to keep them protected. If that thin oily film is removed, your lips tend to become dry, cracked, sore, red and in extreme cases even bleed. Dehydration is one of the main causes of damaged lips. Dehydration means a deficiency of water content in the body. Your body is in constant need of fluids to keep the body cells hydrated and clean, but if your body is losing more water than its getting then you suffer from dehydration, which in addition to other problems, causes dry chapped lips.
