The bump seems to a form of small boil and it may need a short course of antibiotic to heal. But as you have observered that it is healing, you can wait for 1-2 days if it resolves need not to worry else you need to take antibiotics orally. Meanwhile do not try to pop it, it will be more painful. Take analgesic
and anti-inflammatory drugs to reduce pain. Antiseptic cream can also be applied over the site.
Best Wishes and get well soon
