chronic pain treatment

I've had back pain all my life. I can remember being 16 years old and bending over after a long day working at McDonalds to untie my shoes and my back going out. I could not stand up straight for almost two weeks had to stay in bed flat doing ice/heat back and forth. My back would go out a lot I was told I could not lift over a certain weight and all this other stuff. Long story short lots of trips to the ER lots of doctors flash forward 15 years....

I've been to massage therapy but in order for anything good to come of it I'd have to do 3x a week at least. I've done chiro. but most of the time the doctors are too scared to even "crack" anything due to the amount of muscle tension.

A few years ago I did something to my back that pushed it over the edge the pain was so badly and I was having breathing trouble. The doctor I went to diagnosed it as a pinched nerve and the pain was causing anxiety attacks which was causing more pain. He gave me anxiety medication (alarazapam) and pain medication (flexirl) that did seem to work if I took the anxiety meds first then the pain meds. The pain subsided but never fully.

Since then I have had pain in the shoulder blade sometimes into my neck and most of the time down my left hand. At times my left hand goes numb and gets very cold. I'm left handed and have a 15 month old and pretty much if I use my left hand for one day for the next three to four days the pain is so bad I cannot begin to explain and that's on top of the usual back pain I've just gotten use to.

I'm 30 years old. I've been told by doctors that the x-rays of my back look like that of an 80 year olds. I'm in daily pain no matter what I do and I don't know what to do. Whenever I go to a doctor I feel like they are not taking me seriously or think I'm just trying to get pain meds.

Wow this is so much longer than I would have thought but any suggestions or opinions would be very helpful. I have printed out a bunch of info and am going to the doctor today but I don't have much hope I'm tired of being given Motrin and sent home. I feel like this is more than just little pain and it's gone on for years so at what point does it get categorized as "chronic pain"
