I been having burning sensation on my back and legs what does it mean should i see a doctor for treatment?

Yes: It sounds like you have some irritation of your nerves of the back which may be a radiculopathy (a specific nerve root) or sciatica (several nerve roots that join together into the sciatic nerve). Your physician can tell by your history and physical which nerve(s) are likely to be involved. Based on that he may recommend an MRI or physical therapy or medications.
