Does anyone else have "mechanical" back issues such as spinal stenosis and a spondyloarthritis?

I have lumbar spinal stenosis and just had a steroid injection that lasted 3 weeks for the pain. The pain medical doctor told me that surgery would be next. I keep trying to tell my PCP and the pain doctor that I have pain in my thoracic and cervical spine, my hips, my pelvis, my ribs (when that strikes, I feel like I'm going to split in two horizontally), besides my Achilles tendons, and my shoulder joints. I also have psoriasis. I have had back pain and issues since I was in my late teens and am now 72. I have not had a recent MRI or x-ray of anything for 3 years. I also have Psoriasis on my scalp, neck, and inside/outside my ears. Can anyone else relate? PS My doctors don't understand the stiffness or fatigue. Thanks, Gayle
