Welcome to healthcare magic forum
Thank you for your query
I understand your concern regarding your skin problem
It look like you have bacterial infection
you need to apply antibiotic cream over the affected area.
in severe case you also need to take antibiotic medicine orally.
do not press or popped the lesion as there might be chance of spreading infection,
it is better to consult dermatologist
fo r pain you can take analgesic
I hope I answered your question.
