Suggest Treatment For Osteoarthritis

good day. i am confused, as when i was in the USA i was told i had damage to Brachial plexus nerves, fybromyalgia, and carpal tunnel sydrome. in Greece they told me i had osteoarthritis, carpal tunnel syndrome, rheumatism, and spinal stenosis. in the UK they say no obvious indication of spinal stenosis or any information regarding femoral nerves on my MRI, but that i only have osteoarthritis. i can only work 3-4 hours a day, and throughout my job hours i'm in extreme pain, including numbness, burning sensations, leaving me unable to do anything at all after work. i can't write, or even hold a cell phone. i am currently on 50mg twice a day of diflofenac, 60mg of MST, and 20ml of ORal Morph, and i still have severe pain iin hands, swelling of hands, excrutiating pain in spine, hips, legs, and right knee, continious numbing in both hands. how is it 2 countries found i have problems in my spine with their tests, x-rays etc.,and te UK all i have osteoarthritis, but yet they are sending me to neurosurgeon, and not an orthopaedic surgeon? and i'm confused with their diagnosis regarding spinal stenosis. some advice please. thank you.
