If all tests like ECG, blood, and urine are normal but there is a burning sensation all over the body, it may be related to nerve sensitivity or stress/anxiety rather than a major physical illness, sometimes seen in anxiety disorder or mild neuropathy. Since Deanxit has been stopped, symptoms may also reappear. Continue medicines like Rabeprazole if prescribed, maintain good sleep, reduce stress, and take a balanced diet with B-vitamins. It?s best to consult a physician or neurologist/psychiatrist for proper evaluation and safer alternative treatment if needed.
