[|Human|] I woke up one morning and could feel a big bump on my lower left corner of my lip. It ws like that for a whole day n nxt morning it turned black. I applied vasiline on it n now it started bleeding and the black part coming out and light pink skin is visible. Please can u tell me whether it is due to body heat, as i ususlly get this after i get fever..? But now ther was no fever. And what is the line of treatment for it..?
[|AI|]  Hello and welcome to Chat Doctor, A history of fever and subsequent development of lump near the lip is suggestive of herpes labials. Herpes labials is a viral infection characterized by painful vesicles near the lip region. These vesicles can become hyperpigmented and can bleed also. The virus usually resides into the nerves and becomes activated when immunity falls. Improvement of immunity is the basic requirement to prevent the occurrence of herpes labials. For immediate treatment, topical application of antibiotic cream will help. However, a clinical assessment of the lesion is required to confirm the diagnosis. Thanks and take care Chat Doctor.
