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.
Use ice packs. Icing your swollen joints can also help to relieve the pain. Try holding an ice pack on the swollen joint for up to 20 minutes at a time. Make sure that you wrap the ice pack in a towel first to help prevent your skin from becoming too cold. Never place ice or an ice pack directly onto your skin.
