Can you identify a possible cause for this pain (falling down, for example)? I fell skiing 7 years ago. Fell on my butt and lower back. It almost immediately felt as if someone had shoved a softball down each butt cheek and lower back. That night I could see my lower back in a mirror. There was a black (not black and blue) band extending across my lower back. Got home and went to urgent care. Was sent for ultrasound to rule out any clots. All good. Right calf was very swollen. Was prescribed compression stocking to wear. Swelling eventually went away. Hurt when I sat down, sort of like your description. I say it feels like I'm sitting on two Hockey pucks. Have had every kind of injection, nerve ablation, PT, MRI, CT scans. spinal cord stimulator. I get temporary relief, but even then, I can still feel the hockey pucks. I just had a morphine pain pump implanted about 3 weeks ago. Still at a fairly low dosage, but is helping with a lot of my pain. But, I can still feel my hockey pucks when I sit. No one can come up with an explanation. I hope you can find someone who is able to pinpoint the exact cause of your pain and a treatment plan. I am hoping that my pain level will drop down to a 2 or 3 by the time they get this pump adjusted. Blessing on you, my friend!
