Neurologist said i had mult cerv and lumb radiculopathies but mri only showed thoracic bulges. abnormal arm ncs emg for pinched nerves should i worry?

Not if you are OK: If you do not have any symptoms, then no worry. However, the reason why you got MRI of the entire spine and ENG/NCV must be because you have pain and numbness probably of your entire body. You can have radiculopathies in the absence of disc bulge/herniation. However, having multiple cervical and lumbar radiculopathies without any disc problems means you have something else going on. Keep looking.
