Been having lower lumbar issues since 2009. MRI results since than have shown L4 & L5 slightly herniated, bulging and protruding with annular tears on both discs. For years I ve only had slight aches and pains. Did the chiro & PT route. Even tried meds. Suddenly this past May, I started getting pains in lower right lumbar area radiating down right side into buttock area, down rear of leg continuing down front right knee down to ankle. Went for 3 epidurals and nerve blocking injection. All to no avail. Scheduled for discography next week to determine which disc is actually giving me my issues. After they determine which disc it is, surgery will most likely be scheduled. Can it possibly be something other than the discs giving me my pains and discomfort? Also had xray of right hip which showed calcium deposits on ball joint. Seen 3 doctors so far and all 3 seem to believe it s all disc related. But for some reason, I feel my body is telling me it could be something else. Also had routine blood work all came back fine. Sciatica possibly? Any suggestions?
