My job ( security ) added an extra 3 miles onto my patrol a shift and I started noticing my knees steadily hurting more and more . I complained to a few coworkers but I never told my boss or went to a doctor for it . This week I went to a wedding and it made the injury worse to the point that now I can't walk on my left leg. I'm scared to report it to work and them say it's not their fault since it really is . I thought about faking it and reporting it during my shift tonight but I'm concerned I won't be able to walk far enough to make it convincing. What should I do I can't afford to get injured without comp and my insurance is pretty shitty
