lately i have been feeling strange things like pain in my feet and legs, like a sharp pain in my heal, soreness in my leg. also my feet and hands get slightly numb and get a pins and needles feeling all the time. ive been getting this feeling in my arms as well as all the way up to my thighs, it almost feels like its my veins. i have also been getting a tight feeling in the sides of my throat which also feels like its in my veins.
