Dear Sciatica Sufferer, Coming from my own experience, please go to your doctor and be tested for a condition called Hemochromotosis. It is a hereditary condition whereby the body stores too much iron. It is very easily treated, but is very deadly if untreated. A very common symptom is sciatica and other achiness/tiredness. A very simple blood test is all that is required. Also, make sure the doctor that you see is KNOWLEDGEABLE about Hemochromotosis. Not all doctors are aware of this potentially deadly condition which is very simply diagnosed and treated. I know because I have it!
