I have sudden back pain and have not lifted any heavy items nor have i had any accidents. the pain was evident two mornings ago and still provides great discomfort. iv tried lower back stretches with no resolve. what should i do?

For starters, apply heat to the area and take Ibuprofen. If no relief after a week, follow up. Would need more information to completely evaluate but most likely this is benign and self limited.

I have evaluated many people with spinal conditions. I can't tell you how important a good examination is needed. There are several reasons for back pain, some are related problems in organs. Spinal pain can come from bones, muscles, ligaments, nerve, discs and often is due to inflammation and dysfunction of several of these . You should see a doctor in person
