Hello Doctor,
The pain start on my left lower back 10 months ago and radiates to my left leg.siting,standing and foreward bending was very difficult at that time.i took mri scan and spinal tap and the result shows nothing.then i visited by chiripracter 6 times,then to pijn clinic.the specialist in the pain clinic gave me equidral injection,it gives me a little bit relief for 6 months .also in the next appointment (last December)he gave me rhizotomy injection,but it does not work.the pain started severly again and my right arm power is less.not only that in the last four months i experienced eye pain.specially when i wake up from sleep at the morning my eye became red(like blood)and it less after 30 or 40 minutes,but i dont have fever .even my foot and hand fingers are very cold. what sounds seems it Dr? which types of test should have i take to identify the cause?
