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.
Alternatively, that ice pack can go on your cheek, over the painful tooth. Also, according to folklore, if you massage your hand with an ice cube, you can help relieve a toothache. When nerves in your fingers send cold signals to your brain, they may override the pain signals coming from your tooth.
