It's probably best to see a doctor before things get worse in case it's something that can be treated effectively before it causes more damage.
Is it possible you have carpal tunnel from repetitive wrist motion? Stocking shelves is a repetitive motion. If you do have carpal tunnel, you either need to realize it and stop the repetitive motion and find a different job, or find a way to do your job without the pain flaring up, or speaking to a doctor about treatment options. If it's carpal tunnel, it will only get worse with the activites continuing and the pain will become more and more.
If you're feeling pain, that's the body trying to tell you something. In this case, perhaps to stop repetitive motions and let the wrist heal. Carpal tunnel can heal if it doesn't get too bad. It just takes a while.
If you continue doing activities, you will experience pain and possibly burning sensations. When it gets worse, you may notice numbess on the palm of your hand, or in your fingers. This is definitely not a good sign. Wrist braces can help tremendously, but it needs to be worn for a while. Sometimes immediate pain relief is there and sometimes it will flare up, but it depends on the activities you're doing.
If this is from a possible injury or an old injury then it may not be having the chance to heal properly and causing pain for longer periods of time.
I'm not sure if this is repetitive motion. I've worked at my job for a year and started out as a day shift cashier for about 9 months; i've been on overnights as a stocker for about 5 months. As for switching jobs that's not to much of an option. I don't drive yet (i'm 19 ik it's weird) but where i live if off some state highway so aside from walmart or fast food there's very little else close by. Also my family works the same hours at the same place so i have a ride. Switching positions isn't much help because there are pretty much two options for overnight people cashier or stocker; working overnights is better because my hours are always the same 10pm till 7am, i get set days off, a 40 hour work week (on day shift thats nearly impossible to come by) as well as $1.50 more an hour.
I'm over 20 and I haven't gotten my license yet so no worries - it's not weird. To others it may be, but - don't let it get you down. I can understand how that can interfere with your carpool switching times when you have a perfect schedule.
Cashiers and those who work at jobs in where they type a lot are overly capable of getting carpal tunnel because it's repetitive motion. Although, it has to do also with the posture your wrists are put at. Perhaps follow some tips for carpal tunnel and see if it helps any?
Perhaps take note of when your wrists hurts the most and when it feels better so you can figure out what may be causing the sudden pain onset, and what may be helping it go away.
See a doctor if it bothers you. It's best to probably see a doctor anyway since you're not in pain all the time. If it's something that can get worse then it may be best to see what treatments are available early on.
