Ive suffered with chronic severe back pain, In the lower back just above the buttocks.  On several occasions Ive woke up with severe back pain as well as my skin being very sensitive to touch.  Even my clothing caused pain all over my body.  I am currently being treated with Lortab 10 mg and Zanaflex 8mg.  Ive also taken Lyrica, Doxipen and a few others for fibromyaliga.  Also I am having severe chills and upset stomach.
Dear patient What is your age? And for how long you are having back pain? If It's for long duration and not relieved with medications it should be investigated.  First with X-ray of lumbosacral spine anteroposterior and lateral views to rule out bony abnormalities such as spondylosis and spondylolisthesis.  Next is MRI of lumbosacral spine with screening of whole spine to rule out canal stenosis and disc prolapse. So visit radiology center nearby you and get it done. Till then continue your pain medication. If report shows abnormal findings consult spine surgeon nearby you.
