It all depends on what's causing it.

If it is due to trauma, then after the trauma heals or is surgically corrected and time passes so nerves can heal, then yes, the pain may go away.

If it is due to toxic neuropathy, then after the toxin leaves your body and possibly after time the nerves may heal, then yes, the pain may go away.

If it's due to diabetes, then once you get your glucose in order and time passes and you do things to help aid the nerves healing, then yes, your pain may go away.

If it's due to auto immune process or neurological condition, then you may not heal and your pain may not go away...UNTIL you do something to treat the underlining cause or help the healing process with bigger gun treatments.

If hereditary, then likely your nerves will not heal and your pain will stay.

This line of answers can go on and on for many different scenarios...but I think you get the idea.

So again, it all depends on what it causing it (if that can be found). If you sit and wait for the pain to go away, you may be sitting for a very long time and more damage may occur in the meantime.
