~3 wk ago, sudden calf tightness day after walking rocky pasture not relieved by stretching. under dr. tx for sciatica (presented 4 days post onset w/ traditional sciatica symptoms). calf symptoms went away and returned 2 days ago. is this normal?

I Like MRI: I like a firm diagnosis. If this is compromise of a lower lumbar nerve root, let's see it on an MRI. This may direct treatment/help with prognosis. Under 50 I would expect a disc problem but arthritis of a joint in the back may also contribute. Physical exam can also help show disc pathology but is not as sensitive/specific as MRI. Insurance will also want plain x rays. This may not add much.
