I have had so many changing symptoms and felt like hypocondriac too but it actually made the docs able to put more pieces together. I for 3 months had only left inner ankle/foot pain that was so horrid and still but then my right started in similar but not nearly as bad. Sometimes tingling/numb in my lft arm. The right leg and left arm has been for only a few weeks. The neuro said pn usually starts in one area but can move but usually worse in a certain area. I would voice your concern as its better to be safe and catch it earlier.I understand the fear as I have anxiety of whats going to happen next. I know this is easier said then done but I try to stay in the moment and day. So when the thoughts of fear come I say that or reach out for support. Take care
