You mentioned a work out which to me means you are probably involved in a fitness goal. Low back's can be easily strained again with heavy weight lifting so be aware.
Tune in and listen to your body as you push forward to feel better!
Keep a smile,
Always listen to your body, and if you start hurting during a specific movement, stop. Inform your doctor and discuss options and alternatives for specific exercises. All of my patients receive home exercise prescriptions to accelerate the healing process.
