MRI scan

Hi I had an MRI scan in Jan 2011, results T8/9 disc protrusion which indents the thecal sac with mild cord compression, faint myelopathic signal change, smaller disc bulges at T9/10 T10/11 & L5/S1, & some narrowing of right L4/5 exit foramina.
I have had weakness in both legs & numbness & tingling & also pain since Beg of Jan, 2011,I find it hard to walk around,been offered Physio, but after 3 sessions symptoms got worse,is there anything which will help, or will I get better in time. Surgeon has said an operation wont help. WHAT WILL ?
