I'm 27 and have been experiencing lower back back off and on for the last 5-6 months. I used to do martial arts and my lower back took a lot of beating from the constant twisting and getting Judo thrown, along with lifting weights 4-5 days a week. Now my back often gets aggravated from doing exercises like squats and deadlifts to the point where I'll be in such bad pain that it wakes me up at night. I stopped doing some of these exercises, but still get pain at random times. It's not constant pain, but flares up once or twice a week on average and lasts for days and often comes with tingling. I set up an appointment with a sports medicine specialist today who specializes in joint and muscular issues and knows his stuff about back issues. My concern is I don't want to be wasting the doctor's time because I'm not in constant pain and am reconsidering going in for an appointment.
