Suggest Treatment For Back Pain Not Responding To NSAIDs And Thermal Therapy

I have back pain for about 2 weeks now.I saw my doctor for it. I thought it was no big deal and would get better. It is getting worse I cannot sleep on either of my sides now,it hurts to sleep on my sides.My back pain covers my entire spine from my lower spine into my neck and my shoulders.I am doing heat/ice at home,also a Tens unit,Ibuprofen,Muscle relaxers,Voltaren Gel.I am doing stretching exercises and I am overweight.I don t know what else to do.Are there more exercises I can be doing to help? Nothing I am doing is working for very long.I did not do anything to hurt my back.I get Botox and Nerve blocks for Migraines every 3 months.
