I'll take a different tack.
If you're serious about wanting to keep and drive your Cobra and want to invest the time, effort and energy, then I'd highly recommend a couple of subscription services to increase your body's flexibility and mobility. Two of the premier sites where one can resolve pain, increase flexibility and mobility and prevent future injury.
There are literally hundreds if not thousands, of videos online that can help you drive your Cobra pain free by working on your shoulders, knees, ankles, neck, back, etc.
