"When we develop a bruise, claret escapes from the ruptured capillaries and small veins, and spread into the surrounding tissue," she said. "Information technology is the capillaries of the subcutaneous tissues that make the greatest contribution to bruising."
Co-ordinate to Dr Edwin Chng, the medical managing director of Parkway Shenton, most bruises heal in one to 2 weeks' time, although some may take longer than that. "They start off red, and so turn blue or regal. As they heal, bruises can plough green and yellow".

Although rare, such disorders include haemophilia; factor Two, V, 7, X, or XII deficiencies; von Willebrand disease; connective tissue disorders such as Ehlers Danlos syndrome; endocrine disorders such equally Cushing'south syndrome and hypothyroidism; and blood cancers such as leukaemia and lymphoma, she said.
Take note if v or more bruises occur simultaneously – each bigger than 1cm in size – and constitute not only on your limbs, only also your trunk and other areas, said Dr Yong.
Such blue-black marks tin can also be caused past taking claret-thinning medication to prevent blood clots equally well as deficiencies in protein and Vitamins C and M, said Dr Chng. To rule out concerns, see a doctor if your bruises are accompanied past these signs, he said:

If you're thinking about rubbing a difficult-boiled egg on it, Dr Yong pointed out that it "has not been shown to be constructive in treating bruises."
Dr Chng agreed – especially for the initial few days. "In the start few days, rubbing a hard-boiled egg over a bruise may actually worsen information technology," he said.
That's because the heat from the egg encourages blood menstruation to the surface area, causing fifty-fifty more internal haemorrhage, he said. On the other hand, an ice pack or cold pad would slow down the flow of blood leaking out and pooling underneath your skin.

As for arnica, a herb believed to care for bruises because of its anti-inflammatory and hurting-relieving backdrop, Dr Yong said that "studies have shown that information technology is no more effective than placebo in treating bruising, pain and swelling".
What well-nigh hirudoid creams or gels? According to Dr Yong, they comprise mucopolysaccharide polysulphate (MPS), which has been used for treating bruising, sports injuries and inflammation. "Existing data suggests that it is unclear if it is efficacious in relieving bruising," she said.

Applying an ice pack and elevating the afflicted limb tin can "reduce swelling and soothe hurting" but it is "unclear if it helps in allowing bruises to heal faster", she said.
HOW AND WHEN TO Ice
If you are game to give cold therapy a go, consider putting a cold gel pack or a bag of water ice on the bruise for 15 minutes every one to two hours, recommended Dr Chng.
