Scared

My mom is a single mother, who works super hard and she has to get up pretty early. Well my leg started like irritating burning if that makes any sense so I kind of was like THATS weird and continued playing a game with my friends, well I went to go to bed and my leg started burning, and like it was worse. So I told my mom which I woke her up pretty late and she has work so I felt super bad. She looked at my leg and she didn’t feel swelling or anything and it wasn’t red. Well I decided to go and try to sleep again and my leg started like stabbing pains and it went from 1 leg to the other leg and then my feet a bit. What do I do?? I don’t wanna wake my mom up again. But at the same time I’m terrified and I don’t want to die or anything.
