Function points were defined in 1979 in Measuring Application Development Productivity by Allan Albrecht at IBM. The functional user requirements of the software are identified and each one is categorized into one of five types: outputs, inquiries, inputs, internal files, and external interfaces.
SWELLING: Swelling is a normal occurrence after surgery and will not reach its maximum until 2-3 days after surgery. It can be minimized by using a cold pack, ice bag or a bag of frozen peas wrapped in a towel and applied firmly to the cheek adjacent to the surgical area. This should be applied twenty minutes on and twenty minutes off during the first 24 hours after surgery.
It is best to keep ice on your tongue as much as possible the first few days. Do not eat spicy food for the first two weeks. You are suppose to keep the longer piercing ring in for 10-14 days time depending on when the swelling goes down. Your tongue will be swollen for a few days to two weeks. If they do not give you a rinse, then you should buy some kind of sea salt solution and rinse with that. You could use Listerine but it is not recommended for the most part not right away. After about two weeks time you can change it to a smaller barbell. I would use a metal bar but acrylic balls. Acrylic balls are less likly to crack your teeth and wear down your enamel. Best way to change your tongue ring is to take the first one out, and replace it with a clean new one.
