hi goblue. i've had eight nerveblocks from my pm dr my first year of being diagnosed with rsd. they helped a little with some symptoms and pain along with prednisone that my neurologist prescribed but after a few months they both stopped helping. after foour and a half years of having rsd it has spread to all my limbs, stomach and mouth. i have lost five teeth due to rsd and have had irregular ekgs with my heart, ostopenia in my hips, stigmatism and blurry vision in both eyes and just had a mamogram that showed that i was at higher risk for breast cancer now because of dense breast tissue. i also have had sores on my scalp for nine months from rsd and may need cortison injections in my feet because of rsd spreading there. after four and half years of having rsd i've found that pain and antianxiety meds that my pm dr and pyschiatrist prescribe along with a home exercise program that my pt prescribed help me deal with this monster a little better. having this support group also helps alot. hope your nerveblocks and steroid injections help you to feel better. soft hugs.
