Be careful guys make sure to get your back's x-rayed and fully checked out by your doc. Cuz last week I just found out that from weightlifting or breakdancing ( I dunno really ) that these 2 bones in my lower back snapped little bit... And whats even worse is that I didn't even knew that this had happaned. I had little pain and irritation at times but it was managable. He even said that If i let this continued for few more years that i my nerve all over my lower body would be damaged. So for now I cant play basketball, weightlift, run or do anything that puts pressure on my back sucks!!!
