I have developed a very debilitating condition.

The back of my neck always feels very hot and 'burning' - it is as if a hair dryer or a fan heater is being held against the back of my neck!

I don't have this at night but it starts almost as soon as I get up and then lasts all day.

On most days, this hot/burning feeling then spreads upwards to my face and also downwards to by chest and back. I then feel completely 'zonked' out (finding it difficult to work and concentrate) and can only get some limited relief if I go outdoors (but not on a hot day!) or work near an open window or in an air-conditioned environment.

I feel as though I ought to be sweating profusely but there isn't one drop! I use an aural thermometer and my temperature is always within the normal range.

I have had tests and one of these suggested that I may have small fibre neuropathy. I am waiting to see a SFN specialist.

From my 'Google' reading it seems possible that I may have 'non-length dependent small fibre neuropathy/ganglionopothy' - but I may be barking up the wrong tree!

Has anyone with similar symptoms to mine had this diagnosed?

Welcome Jeffers.

Are you taking a serotonin type antidepressant? Excess serotonin can cause heat in the head and neck like that.
