How Can Backache Be Treated While Suffering From Bulging Disk?

I was diagnosed with the following after spending about 20 visits with a psychologist: ADHD, PTSD, Severe anxiety,depression, bipolar and early onset dementia. I went to a seconf psychologist and he confirmed the original diagnosis. I am seeing a psychiatrist who reviewed those findings and he has me on the following drugs: Effexor 250 mg, Xanax 1 milligram up to twice a day, Aricept, Nemenda, trazodone and divalproex I am not any better aftwe 5 years of this regime. I cannot exercise as I was in another accident and I have bulging disk in L3 _ L5 and S1. I cannot take any more steroids (I have 4 epidurals and 4 trigger point injections and since I have type 2 diabetes I have complete panels taken every 3 months and when I had blood test done after the above procedures and both my liver and kidneys was way off course. Family doctor told me to not take steroids because of the afore mentioned. I have been to a therapist and chiropractor for more than 4 months at least twice a week. I need to know if there is any other treatments for back pain as the two ortho I have been to says the bulges are definitely there but they cannot be fixed with surgery.
