Hi there.
Sorry to hear about
your pain but I can sort of relate to it. Recently I had found myself with immense neck and back pain and went to the doctor, sent me for an X-Ray and showed cervical lordosis in my case I have no curve at all in my neck, then got sent for an MRI which showed nerve compression and slight bulge on disc. I am only 18 and I know that this pain at such a young age seems horrible.
You deff ask your doctor for tests to find out exactly what is causing the pain, I am still trying to get my physio sorted which is apparently going to help me.
Good lucky when you go back to the doc. I hope you get answers and help from them.
