Question
In plain everyday English could you translate the Diagnosis from my medical file?

Primary Diagnosis- 847.2 Lumbar Sprain/Strain

Secondary Diagnosis- 724.3 Sciatia Neuralgia or Neuritis

Tertiary Diagnosis- 739.3 Nonallopathic Lesions of Lumbar Region, REC

Answer
Dear Leann Antey,

Though such diagnostic impressions are outside the realm of non-therapeutic straight chiropractic in their use, my specific field of expertise, and I offer no comment here about their accuracy or appropriateness, the terminology you're asking about would loosely translate to a low back injury with pain down the leg.  These are terms associated with therapeutic fields.

I hope this is of use to you.

Sincerely,
James W. Healey, DC
