hi Cancerconcer1 i know you can by co/codmal 8/500mg over the counter at a chemist try taking them but you may find you get constipation but they are a good painkiller a bottle of lactulose will help with constipation if these do not work ask for a referral to see a Neurologist as you seem to be going nowhere with GP or consultant
hope things get better soon
best wishes ScottishTerrier
