Pain in bicep

Question
I was playing rugby when i got tackled i landed on my right shoulder my biceps started hurting but not lot because i had lots of adrenalin.
After the game my arm was in pain i was not able to life my right arm without pain and was only able to lift my arm 28degrees
The next day i was only able to lift it 49 degrees i talked to my coach because i thought i popped my shoulder. but i didn't he said its probly only sore or i bruised my muscle.
Its been 5 weeks already and when i lift my arm up all the way and make it go back as if i was stretching it hurt my biceps.. I'm not sure what it is. I don't know if i tore my muscle or its strained? I'm  just not sure can you help?

Answer
GO TO A DOCTOR!

What youdescribe could be anything from a muscle strain to a broken coller bone or even neck.

Do not train, play or do anything else until you go to a doctor, get scanned /x-rayed and diagnosed.

Never put off going to a doctor as soon as you have suffered an on-field injury!
