Grade: 1
Lumbago. Not being careful enough while lifting weights (leg press). Voltaren 50 mg x 3, minimum 2 days or until symptom relief. Pain primarily while sitting still. No pain during exercise.
Voltaren immediately and normal exercise is key as long as the back i not "locked". In the latter case, it would be appropriate to start up with Voltaren, see a physical therapist or similar and get help to manipulate the joints in place the same day, and then start up with exercise.
