Muscular or disc issues? I had a pretty bad herniated disc almost two years ago. Had to walk with a cane for a couple weeks and didn't totally heal for a few months. I am very cautious now when I start to feel any pressing of the disc on my sciatic nerve. I will rest it, ice it, then heat it up and use the stretching pillow and do other stretches to try and nip it in the bud right away.
