I was sitting on the ground and when I got up I hit my spine around my t10/t11/t12. The table s edge was almost between the two vertebrae and it caused a sharp burning pain. After the initial numbness and burning subsided I noticed I still have a dull throbbing pain and a welt on the part I hit. The welt has not decreased for an hour even with ice on it. I have spondyloarthritis as well. I m sore and throbbing in my back but it doesn t hurt to breathe or move only the pain mostly in the location I hit and the muscles around it. I do feel pain and stiffness coming on but I think it is the spondyloarthritis kicking in from the inflammation of the impact. Would you say it s safe to assume my pain is muscular? The welt concerned me. I m a 28 year old female.
