hello and welcome to hcm forum shely,
i would be glad to answer your query,
first of all i would like to inform you that,you should never prick or even touch an ulcer, let it heal on its own, usually it takes 7 -8 days to resolve. In your case, ulcer was pricked, this led to spreading of infection ,therefore 2 new ulcers have formed.
i don not know whether you have any medical history or not, neither have you mentioned anything about your personal habits.
i would suggest you to visit your doctor so that he can prescribe you oral antibiotics
and topical agents to apply.
capsules will help prevent them from coming back,
as for dry,chapped lips
you can use a lip balm/chap stick.
i wish you good health,
