Feeling Numbness In Extremities, Tingling In Back, Loss Of Coordination. Blood, MRI, Urine Normal. What Else Is It ?
Although there are very reasons for your problem and the list is exhaustive and also the fact that your various blood tests and urine tests have come negative and also you are undergoing MRI brain and spinal region,I will like to restrict myself to the causes other than you have been tested for.
The causes can be due to peripheral neuropathies like
Alcoholic neuropathy
VIT B 12 and folate deficiency
Rheumatoid arthritis
Chronic inflammatory demyelinating neuropathy
Amyloidosis
Peripheral vascular disorders like
Burgers disease
Polyarteritis nodosa
Chronic poisoning like arsenic poisoning
Although your doctor must be looking for various causes but I will like you to get specifically tested for VIT B12,FOLIC acid,calcium,iron as their deficiency is more common at your age.
I hope to have shed some light on it however you can revert to me for any further query on this issue.
Thanks and best of luck.
