Hello doctor, i'm suffering with my lower back, it pains a lot, i can't stand for too long, my right leg gets numbed, what is the possible cause of that?

Back and leg: If you have pain in your back and also numbness or pain in your leg, the nerve that goes from your spine to your leg can be pinched - this can be from an injury, a severe strain. Right away you can apply ice to the area for 20 min and repeat every 1-2 hrs. This will reduce inflammation and help the pain;with you having leg symptoms, I would see your doctor for a closer look to focus your mgmt plan
