I've had buzzing in my feet for years now, sometimes it travels up my legs and can affect the whole body - especially at night. For the last few weeks I've been getting burning feet - it's really uncomfortable and results in "restless legs" in bed...
I also have had major changes in whole body sensation - everything is dulled down - I used to be really ticklish, but not now, barely notice...
I just bought some "diabetic" socks - which are supposed to be less restrictive on the feet. I understand that the feet are very vulnerable in people with diabetes problems, so I am starting to take more care now, before anything else gets worse.
