Since years I've been having recurring lump in my chin-cheek area. Since a few months it has not gone down at all. The lump is a hard mass within the skin and tends to change positions very gradually sometimes. It is extremely painful and is spread out. The swelling is at its worst when I wake up in the morning. The area tends to be slightly warm. It often seems aggravated around my period dates but doesn't subside easily. I'm applying Retino A cream twice a day and I don't see much difference. I'm unable to identify it and it's cause. Please help.. Thank you very much.
