Is this enough to get my SSI?

I had a spinal fusion and it is healed. My facet joints have shifted due to arthritis. I have arthritis from T6 to L5 S1. I am also obese 264lbs. I also have tachycardia. The doctors can't keep my heart rate and blood pressure under control. I take 3 different heart medications, Fentanyl..which is 80 times more potent than morphine for pain, xanax and hydrocodone for breakthrough medication. I also take gabapetin and xanaflex..muscle relaxer. My current mri shows the fusion has healed but my back hurts everyday. Probably the fusion and arthritis causing the pain. My doctor wrote a letter stating I am unemployable for a minimum of 2 years if not permanently and my heart isn't at a functional level. I have been denied twice for ssi and that happened before my surgery. I now have a lawyer but she is worried because the new mri shows that the fusion has healed. I have depression as well because of the pain and my son has Autism. I know you can't predict the future but my hearing is on the 19th and I want to know what others think, will I get my SSI?
