My upper lip is swollen since childhood. i don't know what condition or disease this is. what should i do?

Share your concerns: If this is something unique to you, and not present in other family members, then it could just be unique to you. If you had an injury/trauma to the lip, perhaps it's underlying scar tissue. Share your concerns with your doctor, so a plan of action can be devised whether to watch and wait or do something more. Hope this helps.
