While rushing on a busy crossing in the city I fell down on the tarsealed street. The skin on both my knees ripped tearing through my stockings and bones were exposed. I applied antiseptic cream and plaster but the next day I am unable to bend my knees and very painful walking. Thick blood oozes out then dries up. Can someone suggest a fast healing method. I hate missing my gym and week-end dancing. Want to get better quickly.
