Since 2008 I have been experiencing intense pain that throbs and radiates from the bottom of my spine up to the bottom of my skull. It would happen infrequently until about a year ago. It's now happening daily. The intensity of the pain is so high, while it's happening I have to remain completely still without so much as an in/exhale. Each time it happens it lasts about 30 seconds or so. I did have a lower lumbar fusion in 2001. I developed spinal stenosis about two years ago. Other medical conditions I have; psoriasis, psoriatic arthritis, asthma, pcos, Bronchiolitis Obliterans, Nash, degenerative disc disease, migraines, and gerd. When I bring this up to my doctors, not one has an answer for me. It's getting difficult to handle, I'd love any info I can get.
