Upper back pain. After mri is normal?

F 28, Diagnosis-Upper back pain(just below neck) shoulder bone area horizontally...ok when iam lying on bed...when I sit or do work pain only in that area also when iam laying at night if iam moving around iam feeling pain in that area so much Medications-Many multivitamin,pain killers used Tests-All blood tests normal (Cbp etc)Vit d3 16 for which took 6 months course ,esr 28.MRI normal . Duration-since more than a year. Consulted doctor yesterday he is saying to get an X-ray done is it necessary as I have already taken an MRI instead of X-ray as I have history of 3 head ct scans one chest hrct scan 3 chest X-rays one throat X-ray all were just taken due to my fear of something serious but all were normal and one thumb X-ray due to my injury on thumb ..So iam already on a high radiation side in this small age .Plz suggest what may be the reason Note-I use mobile phone a lot while lying on bed most of the time is it due to that ...Should I go for X-ray after MRI is normal ?
