Severe upper and lower back pain

Patient: I am having severe back pain in both my lower back and upper back between my shoulder blades. The upper back pain I have had for years but has gotten worse in the past few months. My doctor has done an xray, bone scan and ct scan all coming back normal but the pain is just getting worse. The lower back pain just started about a week ago. I have tried taking ibuprofen, tylenol 3’s that my doctor prescibed me, heating pad and ice with none of them working to relieve the pain.
