Cuts and bruises are not specifically a disorder but can fatal if not treated. However, wounds, which are on surface of the skin, heal naturally and require very less treatment but for some deep wounds, we require lot of care, so that infection does not bread.
Well there are different types of wound and different cures too. Nevertheless, things have to taken care for the wound, which are deep and very intense; one has to go for some Tetanus injections or so. Cleaning of wound is very important, with water and then applying some antiseptic, otherwise a scar can form or even wound can grow more. Removing of residues and diluting the bacteria, that form from injuries is the reason for cleaning a wound properly.
Damaged soft tissues or bones under the skin cause bruises. What happens is the blood collects under the skin causing the skin to turn black, purple or blue. Lot of pain and swelling is the result. However, we can reduce pain and swelling by applying ice or a cold compress to the injured area. Bruising can also happen after any traumatic injuries or problem with blood clotting in some people. Bruising is not big concern and can be treated easily but if it is a cause of any underlying medical condition, it needs a treatment.
Bruising can also be the cause of Vitamin C deficiency.
