Sometimes I get burning sensations on different parts of my body that come and go. It can also be described as a stinging sensation. I get them on my ears and my neck and near my eyes. I also have burning and stinging on the sores I get on my body, like my ears and neck and arms and back and head and buttocks. (bed sores). They come and go too. I don't know if its the rsd spreading or just nerves misfiring. I know that I have rsd spread on my limbs and stomach because I have external as well as internal symptoms and pain that never goes away. It's a contant feeling of burning and stinging. I hope you feel better soon. Take care.
