hello there.. welcome to health care magic , thanks for your query, 1st thing i like to emphasise is that you are not supposed to do driving in your 5th post op weeks.. you have to avoid such activities which increases stress on your cervical spine.. like driving for atleast 12 weeks post op, secondly if you are having bony spurs also called osteophytes indicates soft tissues inflammation around the cervical spine, so your symptoms and history suggest that your are having a radicular pain in shoulder due to bony spur and herniated discs are contributing to the symptoms. may be your doctor didnt remove the spurs and didnt operate on herniated discs cause may be they are not severe enough,, i think you should start doing round the clock physiotherapy for neck like short wave diathermy and interferential therapy. along with tab prelogic 75 mg once at night and not neurotin. and get a test done called nerve conduction study of left upper limb. follow this for about a month and let me know. thank you..
