To update you on day 2 of the new tDCS protocol I am using:
Went fine again - used the same new sponge electrodes I got with the conducting gel - no side effects and no problems

My wife was tired afterwards - a side effect of the treatments I have read about. Did indicate that the pain has changed some in nature - some reduced swelling and a change in the nature of the pain similar to what she felt while doing the Ketamine infusions. We will see how the next few days go. Hopefully, smooth with some improvements in pain. Will keep you all posted and will start a new thread on the protocol and research in the area.
