Would a cat scan show anything? I have been having some strange symptoms over the last 3 years. main being dizziness/light headed, fainting, poor short term memory, slurred speech, and strange feelings in my legs, muscle weakness, fevers, tiredness, and a strange rash on my hands and heel. The dizziness/light headed feeling is constant, all the time, never have a break from it. Its so bad I am not able to work full time anymore. I have had blood work done, saw an ENT, had my heart checked everything was normal. The only test that wasn't was when my doctor did the test where I walk a straight line, follow his finger, and all those other ones, I failed. He sent me for a CT scan with out contrast and it came back normal. Would a CT scan show anything abnormal like MS leasions? I am very worried about this. With the symptoms I have, I am not able to live everyday life like I used to. Even going out to the store to get food is a hard. I can't even drive anymore. There are so many symptoms I could list so I just listed the main ones. If anyone can give me some advice I would love to hear from you.
