hi and welcome to the support group -
just an FYI: WEBMD's guidelines prohibits us from listing personal information i.e., physicians names, hospitals, place of employment etc., just wanted to let you know this. describing job duties etc., is fine.
Question for you: Since you unload a truck is it possible that you hurt your back at work? If so, have you filed a worker's comp claim?
Having a worker's comp claim may be handled differently as there are a set of doctors with the worker's comp insurance company that you would be referred to see.
If you did not hurt your back at work then you should see a spine specialist in order to be properly diagnosed - see either an Orthopedic Spine Specialist or Neurosurgeon Spine Specialist - this does not mean surgery but they are the best at diagnosing back/neck problems. Sciatic nerve problems may be caused by a disc pressing on the nerve root, but the spine specialist will be able to examine you and let you know what is going on - they can also let you know what treatment options are available.
your primary care doctor can refer you to a spine specialist or there is a search engine at the top of this page: DOCTORS - just type in the information and it will give you a listing in your area.
I wanted to add when sleeping try using extra pillows - between your knees when sleeping on your sides or under your knees when sleeping on your back - this will help keep the spine more straight and may lessen the pains some - AVOID sleeping on your stomach as this will add to your pains.
Hope this helps - please keep us posted as to what you find out - take care - Joy
