“What can I do about chronic neck pain?”

Poor you. It’s very painful. Probably due to your job it sounds as if it is repetitive strain syndrome in other words your posture ,your job , is contributing to your discomfort. Please have a proper examination to ascertain this is indeed the problem and nothing else such as arthritic changes cervical changes etcetc. A Physciatrist is a good start who will get an accurate diagnosis. From there treatment may be anti inflammatory medication nerve block physiotherapy neck brace. In the meantime check when the pain is worse. Night time. How are you sleeping is it worse in the am. ? How is it during the day. ? Is always very painful ? is it worse after working ? or during working is there a time it feels better ? .how are you sleeping it’s a good idea to try and immobilize your neck giving it a rest. You can get a cervical collar. This is used to rest the muscles not as a crutch. Do get your neck checked out. You are young and recovery ought to be excellent. Many people as I say are google drs. They self treat without understanding the underlying problem. Don’t do that. You can use heat and ice alternatively if you have inflammation. I hope this helps please be sensible.

You should see a physical therapist of course! Your additional medical history will impact treatment options. Saunders makes a home traction unit but it's expensive and not guaranteed to work. I'd go get a consult by a PT.
