Suggest Treatment For Herniated Discs In The Lumbar Spine

Three months ago I was diagnosed with herniated discs (3 to be exact) in the lower lumbar of my spine. I have been going through physical therapy, visiting twice a week, and found some relief with a cortisone/steroid shot about 1.5 months ago. I still am having achiness, but it is more muscle aches. My legs are sore, my abdomen is sore and my rib cage is sore after intense exercise or a grocery run. I want to get on with my life, and get back to my life. Any suggestions on how to make the aches and pain go away?
