Burning sensation may be cause of any nerve related problem or
diabetes also cause the same.
If any nerve is compressed or inflamed in spine that also can cause thae same feeling.
1st you should tested for blood
sugar and then MRI of spine if blood sugar is normal.
If blood sugar is Hugh then go to Diabetologist.
But if you see any problem in spine then 1st go for physiotherapy and anti inflammatory drug prescribed by neurologist.
