The result of my MRI of cervical spine is-- 1. Paracentral disk bulge at c5-6 level with right side neural canal encroachment seen what does it mean..

C5-6 Disc. A disc herniation at c5-6 will result in symptoms from the c6 nerve root. The patern of pain and numbness usually extend into the thmb and index fingers and weakness, if present, is typically in the right biceps muscle. A nerve root block can be of benefit and if the symptoms are not improving, surgical treatment can be considered.
Possible arm probs. If you are having right arm pain, weakness, numbness, or tingling, this might be the cause. Check with your ordering doctor and/or spine surgeon.
