Even before you go to the doctor you can already know if you have any kind of neuropathy through different symptoms that you might be experiencing.
There are many different kinds of Neuropathy. For instance, symptoms of peripheral neuropathy might be different from small fiber neuropathy symptoms. It is important for you to take note where the pain or other sensations are coming from. There is a chance that what you are experiencing is not even related to any form of neuropathy.
The symptoms include pain, numbness, or the common pins and needles that we feel on our arms or legs. If any of these things that you are feeling are unusual and recurrent then you should consult your physician right away. It is better for it to be diagnosed early.
But the best way to be diagnosed is still to go to your doctor. He/She may perform an EMG (electromyography) or a nerve conduction test to see how fast the nerves are transmitting impulses. You may also get a blood test to see if there are any vitamin deficiencies.
