Hi, welcome it would be nice if you could describe your wound, such as, is the skin broken?
color of the skin, can you move your limbs
? has there been bleeding.
i will hazard a guess that it is a superficial Haematoma
, which is collection of Blood under skin and is visible to the naked eye as Bluish Black sometime Greenish Skin, it maybe
painful or maybe not. Hot packs for 15-20 minutes a day Painkillers i prefer Paracetamol
500mg 2-3 times a day, Haematoma usually subsides in a couple of weeks.
