I have a problem with tingling down my left arm and it is because I have a herniated disc in my neck.
If your dr ran tests and everthing came back fine then don't worry. Anxiety is horrible but you can overcome it. It isn't easy but it can be done.
I hope you feel better soon.....
I often gets this,mine is nerve damage.
If your Dr. said "nothing to worry about". Then why worry? I had anxiety so bad my left ear was tingling for days and days. He told me it would leave as soon as my anxiety left. And it did. =) Anxiety can do a lot of strange things to us. Trust your Dr. okay?
