Excessive pain in triscep.

I play badminton frequently(almost 5 days in a week).Recently I have changed my style of playing and most of the time I apply muscle power for smashing.After one or two games,there is immense and extreme pain in my right hand triceps,elbow and lower biceps.The is such unbearable that I cannot lift my hand or continue playing further.I suffered form pain even when I did not change my style of playing but that pain was less and not prolonged.I cannot stop playing badminton since i have professional aspirations and I play an advanced level game. I apply Iodex/Moov and then continue the next or sometimes I apply hot water/steam to the effected area. At times, I have the feeling that may be I am applying excess of muscle power. I should have done it from the shoulder and the wrist.I am feeling helpless and very disappointed as I have to come out of the court very soon everyday and that my training is getting affected. It is very disheartening.
