Body Mass Index (BMI). Body Mass Index (BMI) is measure of body fat based on height and weight that applies to both adult men and women. BMI does not differentiate between body fat and muscle mass. Therefore, body builders and people who have a lot of muscle bulk will have a high BMI but are not overweight or obese.
The bump: or hematoma as we call it, can last for 1-2 weeks. Sometimes it gets slightly worse before it gets better. If the child is acting normally, and not vomiting uncontrollably, she should be fine. If she starts doing those things, call your pediatrician.
Report Abuse. First of all...if the tick was alive and walking...you got the head. not too many of God's creatures walk without a head. And it takes FOREVER (2 to 3 months) for the bump to go away....I know...I am a country girl nursing a tick bite as we speak and have had too many to count. They say if a serious rash or bullseye shows up within 48 hours...get to the Doc fast and get some Doxycycline.
