Thanks for the query.
I have gone through your problem, and by the description of it, it looks like an abscess
, that means there is an infection and it is going to become filled with pus and it needs to be looked at by a doctor and treated.
Your doctor will examine you and will tell you if it is indeed an abscess and he would advice you to get the pus removed by a small procedure. These decisions can only be taken after a physical exam, you should definitely see your doctor at the earliest. You can not ignore it.
Please do get back if you have any further queries.
