Obviously don't know your circumstances, but living with pain of any sort is just so demoralising! Have you tried the likes of Sapphire Medical Clinics etc for prescribed cannabis meds? I get prescribed actual weed but also a tincture of 20mg/ml THC and 20mg/ml CBD and the stuff is a god send for my wife's rheumatoid arthritis. It's something like 50 quid for the intial consultation, and then 50 quid every 3 months for a check up consultation. Tincture is 30ml for £100 and that lasts the whole month.
