Thanks to everyone that replied. I am going to see my GP this afternoon. I am positive it has anothing to do with my footwear. A few years ago I was diagnosed with osteoarthritis - quite bad - and round about that time I felt as though I was walking on cardboard lumps. But I put it down to my back condition. But when that walking on cardboard lumps got worse and the tops of my feet started to feel stiff and tight I mentioned it to my GP who said it was probably PN as my circuation was 0k and it was definately not my back as it was in both feet. That was 3 weeks ago and what is frightening me is the feeling of tightness/covered in glue/ fat numb toes is creeping up my shins. It's there in my feet still - I seem to have a numb patch at the back of my two littlest toes on the ball of my foot -but that tight numb feeling seems to have gone quickly from around my ankles to up my shins. I feel it mainly at the front. I'm scared that it will spread all over my body until I cant feel anything at all. God I am so scared. I will tell you what my GP says this afternoon.
