Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain a small bump can be due to a few reasons like:
1.Bacterial infection..
2.Viral infection causing Cold Sores..
3.Sun blister due to overexposure to sun..
4 Fordyces spot..
5.Acne.
As there is scab formation and you continuously injure it by trying to remove it, it is getting bigger as it is not getting chance to heal naturally..
You should not touch it again and again and once should
consult a dermatologist to get evaluated for the exact cause of it..
In case of Bacterial infection you should apply
TRIPLE ANTIBIOTIC Ointment over it at least three to four times a day..
In case of
Herpes abreva which is not an over the counter antiviral medicine so instead of it you need to apply an antiviral ointment and Oral
Antiviral Medication has to be taken..
As
sun blisters heal themselves and fordyce's spot are harmless they do not require much of Medication ..
You can do cold compresses over the lip..
Apply thick coat of Petroleum jey over lips as it will soften the scab and will help in healing faster..
Avoid licking and biting the lip..
Hope this information helps..
Thanks and regards..
