A sural nerve biopsy may be useful to enable the clinician to diagnose the etiology and underlying pathology of patients presenting with symptoms of a peripheral neuropathy, when no clear underlying cause has been determined with conventional assessment such as electrophysiology or quantitative sensory testing.
The Best Wildflower Hikes in the Great Smoky Mountains The Great Smoky Mountains are home to more than 1600 species of flowering plants. During each month of the year, some forb, tree or vine is blooming in the Smokies. During the spring, wildflowers explode during the brief window just prior to trees leafing out and shading the forest floor (from about mid-April thru mid-May).
Swamp Sunflower. Golden daisy-like blooms open on this native wildflower in fall and linger until frost. Swamp sunflower blooms best in full sun but can grow in part shade, although plants will be lanky. This perennial grows 36 to 72 inches tall and wide and thrives in moist soil but can survive in well-drained soil, provided you water occasionally. Plants are hardy in Zones 6 to 9, but readily seen to Zone 3.
