Magrego,
Forgive me if you think I'm overstepping here or reading wrong between the lines. As I see it, you're living with disabling pain but you seem reluctant to 'find your cure' if there is such a thing.
You're very young and living this way is a waste of your time and life. Getting another opinion from a gp is not the same thing as a specialist who knows spines and can definitively tell you what is going on and give you a plan to fix it (unless this step is necessary for insurance reasons).
Chiropractic will more than likely make you much worse unless he's a DDD or herniated disc specialist but even then, I'd be
very weary.
I'm not a doctor and have absolutely no medical expertise but... the tingling and or numbness you feel is/are probably nerves protesting something touching your spinal cord, regardless of the cause. This should be given priority. Nerve damage is unpredictible and can become permanant. I'm also not suggesting surgery is your only option but if necessary, most of us have one shot to get it right so choosing your doctor carefully is the highest priority.
To show you what can go wrong, my chiro put me into an emergency surgery situation. My highly respected neuro surgeon offered no options in my surgery and only post surgery did he tell me the downfalls... and never explained the risks involved with my second surgery.
Magrego, I realize my words are scary and that's not my intent but you do need to take charge of your care. You need to educate yourself in exactly what's going on both in your lumbar and cervical spines and find out the possible effective treatments for both. You either need to find the absolute best doctors in your area or like many of us, travel to those who are tried and true.
Mark basically told me the same things but over the course of several phone conversations instead of bluntly on a forum page. Please feel free to call Mark -
GPN Artificial Disc Replacement ADR but please take control by learning as much as you can. Suffering in this much pain and this disabled is not the way to live, not if you can do something about it. Whether you want the postion or not, you are your own best advocate.
Again, my apologies if I said more than I should have.
Dale
