My shoulder has been twitching at one spot for 5 days straight now, at rest, all the time. i hurt the that muscle during workout a week ago, but i pushed through the pain. now it still hurts and twitches. should i be worried twitching lasts so long?

You need to rest the area and avoid any further muscle strain. The twitching is likely a reaction to the severe muscle strain. You could also put ice to the area and see if that lessens the twitching. Take ibuprofen to decrease inflammation. If it continues, have your doctor take a look at it and see what other interventions may be needed. Good luck!
