Torn Hip Flexor/ Upper quad insertion muscle…i think

Played a game at the weekend. Warming up i knew something was starting to go but it didnt feel too serious. It was in the hip flexor area/upper quad area.Played through the game and it got worse.It was a big game so had no option.
Afterwards there was huge swellin in the area. Iced it for a couple of days. Going to physio tonight. Thing is the whole of my leg is bruised from my stomach to just above the knee.Is this normal. It looks as if someone got a baseball bat and baeat my leg with it!!!

I cant walk poperly on it either.

However i can do a quad stretch and it doesnt hurt which would lead me to believe that it is not my quadracep that is damaged.

Any help or reassurance would be much appreciated
