Thank you for your query at DoctorSpring.com
I have read complete details of your question .
It looks that you are having shoulder pain after vigorous exercise .It looks that most probably you may have bursitis at shoulder region.
At present you should have a mild analgesic and anti inflammatory medicine like Advil .Do ice fomentation over shoulder.You should also keep yourself away from strenuous exercises for few days.
Hope this will help you.
Feel free to discuss further,
