Cure For Lower Back Pain.net

(I’m a 23 year old male - 6 foot 4 inches and very active).a few months ago i was paint-balling in a forest and as i was running down hill i slipped on a wet, exposed tree root. As i was falling backwards and while my spine was bent backwards i regained my footing with my left foot only to be instantly crippled by pain - about 1 inch to the left of my spine in my lower back. i could barely walk for days and it slowly got better but has never fully recovered. its been on and off for weeks now but recently I’m getting a terrible shooting paint at the point of injury especially after i stand up from a sitting position. the pain gets worse if i move my foot in a certain way or if i bend my neck forwards. does anyone know if this is a serious problem or something muscular/nervous that can be repaired with rest or stretching or anything or i should just get an x-ray?? any ideas on what might be causing it?? any help greatly appreciated!
