There was also burning sensation in my arm and numbness in my hand and foot. All of which was onu right side. Weak type feeling thru out also nausiated and ringing in my ear. Light headed as well. From begining to end was about 5 hrs and for 3 days was still weak. I went to the er within the first hour, the 1st dr. Checked me, ordered blood test (4 seperate tubes), urine & a ct scan Unfortunately his shift ended before the results were in, here lies the problem... 2nd dr comes in says ct looks good, blood and urine test are normal you can go, he never checked me himself or ask me anything. By now you know he decided it was just anxiety, I have had anxiety for 41 years and never ever has this happened. Please help me to understand what happened to me and that its not in my head.
