hi.. don't get panicky... go for a checkup.. if possible a dermatologist.. sometimes an inflammation in a sebaceous gland or sweet gland results in such a lump.. go for a check up and relax yourself.. the doctor would be of best help.. take care..
talk to a doctor. they would know what to do.
You need to see your doctor or go to the ER. Could be an abscess and could need draining and antibiotics. In the meantime, to ease the pain, use hot compresses.
