I am diagnosed with pannic attacks, permanent pinky finger paresthesia, woke up at 2am with whole left side of body numb and tingling. Should I do ct?

Let Dr decide. Best clarify with your doctor numbness on one side is a concern but an examination would clarify if you need a ct. The finger numbness alone is likely a nerve compression at your elbow or wrist. Your dr can eval this to see if any studies are needed.
