Hi @traceyk23, I am new to this group as well. My daughter was diagnosed with CRPS in her left foot in 2017, and experiences severe pain on and off. She was advised by her pain doctor to use a Tens unit. We found one on Amazon, and she uses that when her foot is flaring up. She also uses Lidocaine cream on it, especially at night. Try contrast foot soaks, too. I hope she gets some relief.
