do any of you actually had or have cts? NOT neck disc issues but in your wrist or up your arm (if that's even possible)

i went to the neuro AGAIN and he said he thinks i have cts based on the needle pricks he did on my hand and the phalens test

what i do not understand is,

first of all the phalens test didnt hurt so wouldnt that rule out cts? my hands did tingle during it mildly but i have synovial fluid in my wrists (i had a cyst drained on the top part of my wrist but it came back) and i know that fluid has made my fingers tingle very mildly if i used my hands too much

i had a cortisone injection in my ct and it didnt do anything zero change in symptoms.

he said i need another emg ncv and refused to give me an mri of my arm.

any comments/experiences appreciated, thanks.
