Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that a fluid filled bump on lower lip with dry
chapped lips can be pointing towards that you are suffering from a viral infection known as Oral Herpes caused be
HERPES SIMPLEX VIRUS 1 leading to formation of cold sores which are small
fluid filled blisters.
If the discharge is pus then it can be due to bacterial infection..
You should
consult a dermatologist and get evaluated and get viral culture and sensitivity testing done, Other investigations like Polymerase Chain Reaction etc can also be done..
In case if herpes is confirmed oral and topical antiviral therapy like
Acyclovir therapy can be prescribed to you by the dermatologist to reduce the duration of present infection and get prevent further outbreaks..
Do cold packs over the lips to reduce inflammation and pain..
Apply thick coat or Petroleum jelly over the lips as it helps in lubricating the lips and locking of moisture..
If it is due to bacterial infection then antibiotic ointments can be advised..
Hope this information helps..
Thanks and regards..
