For a long time now I have had numbness on and off in my left foot in the toe next to my big toe. It doesn't seem to be temperature or activity dependant. Until now I have brushed it off and thought nothing more of it but in the past couple of months it has now spread to the neighbouring toe so when the numbness appears it is now in 2 toes. Ordinarily I would just brush this off and live with it but now wondering if I should be more concerned as how long is it going to be before it's all the toes and who knows the whole foot! I have a under active thyroid and on medication and recently had my blood checked and everything fine but I am not convinced. In the last two days I have noticed floating, see-through things in my vision in my right eye. I have got a doctors appointment but not for another 2 weeks. I am 39 years old, female, 5ft 4inches, 73kg. Can you help?
