I expirenced pain in my lowerback a couple months ago, so i did the proper steps by avoiding the workout that caused it pain, heat/ice and streching. The pain is nonexistance but i went to get a physical yesterday and my doctor said the left side of my lowerback is way more define and musclar and that might cause pain in the right side ( where the pain was). so what workouts can i do that will strengthen the right side of my lowerback but at most minimally effect the left.
