I too have been experiencing constant pulling/tightness that began in my face last January and has progressed to burning sensations throughout my entire body. I spent 2 weeks at Mayo ruling out all kinds of diseases and sadly the conclusion is idiopathic neuropathy that has caused centralized sensitization - meaning that my cns has rewired itself and my nerves are misfiring pain signals..
Gabapentin doesn't work for me and I've been taking pregabalin, however it isn't working anymore. Just to sleep I am taking lunesta, Ativan. & Melatonin. But I wake up at several times in excruciating pain.
The pain therapist say in need to let go of the fear that is causing the stress that makes it worse. Sort of impossible to to when your body is on fire.
