I have been working as a preloader for about 5 weeks now, and since the middle of last week my shoulder and bicep have been hurting me pretty bad. Today it was getting to the point I could hardly lift anything it just hurt and felt fatigued. My question is if I go to the doc and they say I cant work could I loose my job? I mentioned it to my sup today but he assumed it was just sore, not in pain. What should I do?
