CarolinaRose,
I'm glad the pain is better today. Hopefully it will just keep improving. The sympathetic ganglia run on either side of the spine a little ways out from it. They would not have been shooting right in your spine but to the side of it. The xray/fluoroscope would have helped them get in the right spot.
Your doctor may not have thought hip discomfort alarming, perhaps that is a response seen on occasion. I think they forget that what is everyday routine for them is NOT routine for patients. Like I said nerves do funny things. I am hoping that for you the pain is related to the pressure they said you would feel. I don't know how much volume goes into an LSB but they are increasing pressure in the area of those nerve roots and ganglia with the fluid they inject. Nerve roots get fussy, Many people have leg and hip pain caused by sciatic nerve root compression of even a small amount from spinal degeneration. I had sciatica just from being pregnant (definitely an increase in pressure!) Hopefully your nerve is just telling you about the local increase in pressure and is going to settle down as the fluid absorbs and the area recovers. I think it is a good sign that some of your symptoms decreased a little as far as swelling and sensitivity. Sorry that had to come with hip pain!
I hope you feel better soon, Sending Healing Love,
