I have the following symptoms: burning feeling in my chest and stomach. numbness, pain and abnormal sensations in the arms and legs (on the left side). muscle weakness and aches. is this neuropathy?

Don't jump the gun: Highly unusual presentation for first time neuropathy. I'd check the obvious things first in what you've said then, move from there. Check to be sure there is no acid reflux going on which can cause everything you're saying. Makesure cardiac status is normal and then, finally look into possible reasons you may be anxious (i.e. New job? College student? Marital issues?) all the best!

Young but not health: At your age you are expected to be healthy and well. It looks like you have excess of stress from some source(s).You need more support from family and friends and reduce the stress in your life. You should go for daily walk every morning and gradually increase the distance upto a couple of miles of a brisk walk daily.This will help strengthen your mind and calm your nerves. You have no neuropathy.

I would see a neuro: Doc for this. Things that have to be ruled out include lyme's disease and ms among other things. Please get an evaluation to set your mind at ease or to get timely treatment. Best wishes.
