What you have,could also be an abscess, and if it is, your doctor will prescribe some medication.Until your doctor checks this
lump,no one can be sure what this
lump really is.Because of your age and because the lump is painful I presume that it has nothing to do with cancer.But please have it checked, so your doctor can do something about the pain by prescribing some medication for you.Good luck and God Bless.
