mim73, ask your GP or the surgeon for MR imaging. It's possible that muscles on the left are adjusting to changes on the right. But it is also possible that you have injury unrelated to the surgery. You might tell your general practitioner that you thing you may have suffered a vertebral fracture. Because of your anxiety and because you might have something else happening either with the disc or the vertebra, I don't find waiting a couple of weeks reasonable for you. And I hope the MRI finds nothing and that you heal without pain.
