Mourning pain

Hello,

i feel pain mostly in the morning, when i wake up and lower my shoulders, i feel pain in right shoulder, it feels like on top of the shoulder, area where it hurts is sensitive and warmer. Sometimes pain goes down thru arm, and i feel discomfort in biceps. Pain first occured in gym, when i was doing my trapezius muscles.
Anyone knows something about it?

Thanks,
Zolja

Sounds to me like you really need to be checked out by a doctor.
