Suggest Remedy For Severe Pain In Lower Back Due To Lifting Heavy Weights

i was lifting in football and we didn t stretch. We were maxing on power clean and I got 210 and it was kinda heavy so I went up to 220 and when I did that my back popped then I felt the pain in my lower back. It s so bad right now. I couldn t even walk 30 mins after. I had to lay down. My friends had to help me to the car and driving was hell. I got to home and I ve been laying down since then. My back butt and thighs are tingling. I don t think my mom will take me to the hospital, they hate to spending money. What do I do. I m in so much pain right now and coach wants me to squat 330 tomorrow. I know can t do that. I can t even do body weight squats right now. Pleas help me
