I wanted to add a few things I forgot.
I am an avid runner (5-6 days a week, 3 miles per day). I have had no issues running since dealing with these various symptoms. I even ran this summer on 85-90 degree afternoons.
I am ALWAYS cold..I sleep with an electric blanket..sit beside a portable heater all day at work..and love sitting out in the sun.
For the past two weeks my fingers have been slightly shaky and weak..I notice this most when typing. They feel the exact same on both hands. Thanks whisperwolf for the above response!
I've been prescribed xanax and prozac. Xanax helped me very much! When I took a pill, the numbness went away..sometimes totally..other times about 90 percent. My doc says it is addictive and only gave me 8 pills..said I needed to be on something else like prozac. Prozac was not good for me..gave me chest pains and blurry vision. Could not sleep or eat while taking it. I've been afraid to try something else for anxiety after my experience with prozac. Could diabetes be detected from blood tests? I would think I've already been tested for it. I was tested for a myriad of thyroid conditions but all came back fine.
You should be tested for Diabetes. Diabetes can cause numbness and tingling.
Also, Anxiety can cause numbness and tingling. Have they tried putting you on medication for Anxiety and see if that helps with your symptoms?
If they are concerned about MS, they should order an MRI. I would insist on seeing a Neurologist.
