I have also noticed that the tingling will increase if I put my hand under high pressure running water.

The second neuro that I went to used a tool that vibrates on my feet. She asked me to tell her when the vibrations stop. Well, they never stopped. She looked at me and said "Do you still feel that" I said yes, but the intensity is starting to fade. She never explained to me what that meant and I never thought to ask.

Maybe I will ask at my follow up in the next few weeks.
