I have had exactly the same experience. Gout followed by tingling fingers and toes burning at night and also more recently tinnitus. I am 58. Essentially peripheral nerve damage. Gradually getting worse over 4 years. Not diabetic. I Did a medical DNA general test unrelated. Said I have a gene that may make it difficult to absorb vitamin B12 and that the Symptoms include tingling feet numbness in hands. Googled b12 symptom and can also cause tinnitus. Then Googled everything on b12 deficiency. It causes peripheral nerve damage if untreated and irreversible if left too long. Some research I read indicated 40% of gout sufferers also have B12 deficiency. My B12 levels are low but in normal range. But u can have a deficiency and be in normal range as the main test is highly unreliable. Google for full explanation it’s complex. Finally Dr agreed to give me a jab. A few weeks ago I got my first b12 jab, too early to know if this will help or if it is just a red herring but have a 3 month course and waiting to see if there is any benefit. Also saw a neurologist a few years ago he thought after an MRI it maybe compression in neck from slumping over keyboard but physio had no effect. Not sure that would explain tinnitus either as ears above neck bit a neurologist might know.
