I have had RSD for 15 years. I have tried nerve blocks radio frequency deadening of nerves spinal cord simulators. different drugs.pt etc. I know have new Dr. he started the 3 injections to see if I got relief. I did get moderate relief not lasting long. Now he has done the radiofrequency thermocoagulation or RFTC deaden the nerve. I have had some relieve but every now and then like 1 time last week and twice this week my pain in my foot came back twice as bad as before but it went away in about 15 min. Is this typical?Has anyone had this done what can I expect?
