LEFT lower back pain

Hello. I am 19 years old.. last night and ALL day today ive had a horrible dull pain in my lower left back, slightly above my bottom.  It hurts real bad to even bend forward the slightlest bit. I have had this exact pain come and go for years. when it comes it lasts about a week.. then goes away.. but it comes back over and over again after so many weeks/months at a time. I will also randomly get numbness/tingling sensations in my whole lower body, basically from my lower back/lower abdomen, all the way down to my feet. this will last about an hour or so at a time. but this does not usually occur with the back pain. so i dont, im not real sure whats causing it.. any ideas??

It possibly due to ligment/tendon injury ,which can lead to inflammation around nervers root area.then your symptomes came out...
