torn bicep

I was playing hand ball and hit the ball with my left hand when I had a snapping in my bicep followed by pain in my bicep, elbow and forearm.
I quit immediately and iced and haven’t played now for three weeks.
I have a huge bruse from my bicep thru the elbow area and the fore arm is now brused and yellow.
It doesn’t seem to hurt unless I try to lift with my left arm and the pain seems to resurface. What are you thoughts?
I played golf this week end and it didn’t seem to hurt then.
Thanks for you help and I look forward to your response.
What is the expected time frame for recovery? Rugga Mather
