Hello
If it is from a cold sore caused by herpes simplex 1, you could ask your doctor for some antiviral medicine to take for a few days.
If not, try icing the area, or try some benadryl or another antihistamine.
If they are severely swollen, please see your doctor for further investigation. You may have an infection that would need a course of antibiotics.
Hope that helps,
Please let me know if you have more questions.
