Primary herpes simplex virus (HSV) infection occurs in young children approximately one week after contact with an infected child or adult.
Signs of oral infection include red, edematous marginal gingivae that bleed easily, and clusters of small vesicles that become yellow after rupture and are surrounded by a red halo. The vesicles coalesce to form large, painful ulcers of the oral and perioral tissues. The oral lesions are accompanied by fever, arthralgia (joint pain), headache, and enlarged lymph nodes.
The lesions typically resolve spontaneously within two weeks and do not scar. Fluid intake (including ice and popsicles) must be encouraged. There are some oral analgesics (such as Zilactin or Abreve) that can be discussed with your personal physician. In more severe cases, oral narcotics, usually in the form of elixirs, may be required for adequate pain relief. Antiseptics may hasten drying of lesions and decrease the risk of superinfection.
The Zovirax has been shown to shorten to duration of infection in some cases. If pain continues to be an issue, then another opinion can be considered.
Followup with your personal physician is essential.
