I had my first lumbar sympathetic nerve block today and it actually helped!!! My foot, which is usually cold, felt warm. The pain improved and I was about 50% improved pain-wise, 100% improved temperature-wise. Of course the muscle atrophy hasn't changed. This might confirm the CRPS/RSD diagnosis. It's already wearing off, only about 6 hours effect, but I am still a little hopeful. Will have another injection on Thursday.
Did they tell you to ice the injx site on & off for 24-48 hours? It helps reduce inflammation. It may take several injx to get better relief. I received 3 for each area, and sometimes the pain was worse after the first one. But after the 2-3 injx I could tell a big difference. Hugs & prayers it will for you! 🙂💕🙏🌼
