Blood Blister on Lip
Blister on lip is also known as cold sores. It is a viral infection that causes small blisters that are filled with fluid to occur on the lips, around the mouth and on the edge of nostrils. It causes pain, itching and burning sensation before bursting to form crusting. It may take 3 to 4 weeks to heal without leaving a scar.
There is no specific treatment or cure for fever blister on lip. After suffering from this infection, the virus remains dormant in your body and it may reactive to cause recurrences of the cold sores. Antibiotics can be used only to relieve the pain and discomfort caused by the blisters. Antiviral drugs such as acyclovir can be used to reduce how often the infection returns by suppressing the multiplication of the virus.
The recurrence of this infection is more common to individuals who are below 35 years as compared to those who are above this age. Its recurrence is not severe as compared to the initial outbreak. It may only show a few symptoms that are likely to go away after some days.
