Chronic pain

I have chronic daily pain in my shoulder and my back for years. I have been to many different specialist and everyone has a different opinion but no real solution. Nobody has told me why it's happening or what caused it(Chiro, massage, acupuncture, reflexology, body energy talk, physio....)

It's mostly like nerve pain in my shoulder,wrist and hand (some days I can't even write or grip). The pain radiates into my low back, knee and foot. Most pharmaceutical make me nauseous. I most use ice, 5htp (melatonin and serotonin) and smoke medical marijuana.

I'm 27, healthy and active. I have scoliosis in my low back for about 15 years now. I have worked in childcare for 10 years. I am getting married in September and ttc afterwards. I don't want to suffer anymore and especially when I'm pregnant and during motherhood. I am starting to feel like I gave my best years to everyone else's kids and that my kids are going to be left with old broke mom.

Does anyone else suffer chronic pain? Has anyone else suffered a mysterious shoulder pain for years? How do you manage it? Has anyone found a solution?
