Hi, Thanks for writing in. It appears that there might be a condition involving the nervous system in your body. The above symptoms like numbness and tingling are associated with conditions of nerves affected in various regions. This can be due to an acute cause or due to chronic problems like neuropathy associated with diabetes or auto immune disorders. History of any other medical conditions and medications that you are taking is important. Vitamin deficiency states can also appear as non specific symptoms as described by you. Please consult a neurologist and get a complete neurological examination done. Investigations like MRI scan brain and spinal cord might also be required for you.
