Hello Doctor! My mother had slipped & fallen down on the floor on the 6th of May. While falling she got hurt on her thigh by a wooden plank, which had resulted in the formation of lump & Blood clot in a particular area. Now its been almost 15days but the lump has not disappeared the skin colour looks normal but the lump is very much hard to touch. Will it dissapear on its own or should we consult the doctor! If yes then which? Please help!
