Dear ryan,
i am so sorry that you are going through such difficulties at such a young age. I am a chiropractor and I hope to give you some helpful advice.
I do not believe that this is all in your head although I think depression and mental issues can contribute to pain and its intensity.
So, you mentioned this began after you picked up some heavy objects, was the pain only in your low back or did it radiate into your legs also? Is the pain continues or intermittent? Do you have pain, numbness, tingling, and/or weakness in one or both legs? You also mentioned you are having symptoms all over your body, is it pain, numbness, and or tingling? Is there any neck pain? When you say your legs give out, is it because of pain or due to weakness?
When did you first have the mri and ct scans done? Have you gone back to do some more testing since the first ones? When you say your legs give out, is it because of pain or due to weakness?
From what you mentioned, there is a definite nerve involvement but I do need more info so try to answer the above questions is possible.
I also suggest that you and your parents do some research and find a competent chiropractor, orthoped or neurosurgean to get second and third opinions. Do not despair, there has to be some explanation to why you are having this pain. Please keep us updated on how you are doing.
