Interesting. I sometimes get numbness in my right ring finger and pinky, extending up the arm. I hadn't thought it might be connected with the anxiety in any way. I'd just put it down to cubital tunnel syndrome from spending too much time on the computer, and my doctor agreed with me and said I should get a wrist rest. I still think that's the case, but I wonder if the worry is exacerbating it.
In answer to the OP, Google is stupid. It can only give you a list of diseases that have the symptoms you're experiencing, and, as studies have shown, it normally gives you the worst ones first! It can't take your case history; it can't give you a physical examination; it can't interpret those things in the light of eleven years of medical training and clinical experience. Your doctor can do all of that, so they're going to be about a million times more reliable than Google.
