 [ Symptoms ] i found a lump on my breast in the spot where my boyfriend bit me could the lump be in relation to the bite  i am worried but i do not want to over react if it could just be some deep tissue bruising or swelling due to my boyfriend biting me [ Disease ] who are you dating hannibal lector yes a bit can cause a deep bruise called a hematoma and this can form a lump for a while it should eventually go away as you body reabsorbs the blood in this tissue and if your boyfriend bites you again he should go away
