hi i got prescribed fucudin cream off my doctor tuesday afternoon! i had a massive lump/spot about 5 weeks ago, the lump went and for about 3-4weeks its just been a red circle spot and slight lump, looked more like a scab, going slightly bigger! i went docs as worried, she said looks like could have been a cyst and got infected! how long should the cream take to properly work! the swelling has slightly gone down but its still red?
