Does anyone have a conclusive answer to why we get numb fingers & toes following a Total Thyroidectomy? Or is it different for everyone. A friend of mine still as a numb big toe on one foot & three numb three on the other foot nearly 3 years following TT. All this numbness fir me only happened after TT. And it's getting worse with numb patches that come & go on after parts of body, ie head & shoulder. My GP says it's just related to op, & the fact that I have a bad back since op (muscular). The muscles in all parts of my back are very tight, even getting a massage only helps a bit. X Ray on lower back shows no abnormality. I'm due to see private Endo & will see what he says. Is it entirely normal or it is something serious? My toes are basically numb all the time, numbness in fingers comes n goes.
