What you may be having is a boil or an abscess and pressing it has worsened the condition. Apply warm compresses,Neosporin ointment and calamine lotion and avoid messing with it.You can take anti-inflammatory pain killers like ibuprofen or acetaminophen. If the lump persists then it will be best to get it evaluated from a doctor as you may need oral antibiotics and incision and drainage.
