1. First, I'd like to know if there is any discharge or other liquid (pus) coming from the lump and how does it look like (bloody, pus, etc.) or is it as ulcer-like? It is necessary to do such determination in order to start oral therapy
2. Next, what type of depilatory methods do you use? Using razors is usually associated with infected hair root. Therefore, it is a must to go and see a surgery specialist to operate the lump to destroy the inner capsule (if present).
Hope it helped!
