Cervical hardware

I had a multi-level fusion with Laminectomy on C4-C6. I have been in quite a bit of pain since the surgery in late Aug of this year. About a week ago I started feeling more pain and the pain has only progressed. I went to ER and they done a CT and found that two pedicle screws C5 and C6 right side had migrated and extend into the neural foramen. I can not get my pain under control. I am having the following problems Neck and back pain, axial pain, muscle spasms, and trouble lifting my right arm.
