Did I pull a muscle?

About a month and a half ago, my right thigh started to feel extremely sore. Laying down and sleeping wouldn't help, cold compress wouldn't help. I took a 4 week break from work for family causes and thought the pain would go away. It was eased but I came back to work yesterday and it feels twice as worse as it was before. When I walk I have a huge limp because if I bend my leg at all it extremely hurts. I work for 10 hours a day 4 days a week. I only worked Monday and yesterday, and each day it gets worse. I can't walk down steps properly, I have to go one step every five seconds or so. When I lay on my stomach or side, my leg feels like there's lumps in it but when I run my hand over it, there's no lumps. It takes me about ten seconds to lever myself to sit down. I need to be constantly kneeling down at work and I can barely do that efficiently. I have to work two more days this week and I'm genuinely worried I won't be able to pull through it.
