This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
Do you mean your back heats up after food?
Since all the scans are normal, this can be due to the sensory nerve related problem.
The heat sensation can be abnormally perceived by the nerves of the back.
Vitamin B12 deficiency, diabetes, thyroid disorder are some of the possibilities.
In many cases, the cause may remain unknown.
What medication you have tried so far?
