I've been trying so hard to pinpoint what is causing this relapse. Is it possible that it is PTSD from the 1st episode of this "injury"? And the twinge that I felt during the yoga class just set off a firestorm of fear/terror that exacerbated the symptoms? My MRI is clear. Chiropractor thinks it's central (from SI/L4/L5) and podiatrist thinks it's tarsal tunnel syndrome. But he (podiatrist) said something that rang a bell. When I asked him about the extreme sensitivity, he said that it must be a conditioned response from the last episode. And this was my 1st appointment with him! I keep asking myself what my life would be like now if I hadn't taken that stupid yoga class. Everything was going great. I was happier than ever. Then bam! Honestly, my "rage" is directed at me. I'm frustrated and disappointed that I did this to myself again. How do you go about healing when you're only mad at you?
