persistent neck spasm

19y female

hello !! first off - first post, so i apologize if this isn’t forum standard or anything !! im currently not in a situation where i can afford a doctors visit / transport there reliably, so i thought to whisk my worries off to the internet to avoid more constant appointments ^^

i’ve been dealing with recurring neck tightness / pain since around late september 2025 due to prolonged screen usage that i’m still trying my best to work on, but i’m still sat at my computer for over 12 hours a day sometimes, definitely at an awkward angle due to my monitor setup - been to the doctors numerous times for it on and off due to anxieties all with the same (fortunate) result of while it doesn't feel like a lump or anything bad is in my neck, the muscles are very tight and spasming. i even had a swallow study conducted which should’ve quelled my anxieties about it at all having nothing there as while the pain hasn’t been as bad recently, it still hurts horribly to the touch some days and feels like a mass of something is there in my neck which has sent me down a spiral of overthinking that the swallow study didn’t catch something it should’ve

test-wise, i had my thyroid tested just a couple months before the muscle spasms started, coming out as normal and my doctor said that means my thyroid is still fine. i also had an ekg done which also came out as normal - alongside, as mentioned, the swallow study.

the only other symptoms i’ve been dealing with as of late, possibly or possibly not related that i felt would be important to mention, have been a persistent vague sore throat (not sickness wise and not really bad- however, my throat tends to start hurting when i talk as i have been mute for a majority of my life, and i understand that a sore throat can swell up lymph nodes) for the last few days - and very persistent heart palpitations that last for a few minutes at a time throughout the day over the last 2 weeks, that have happened upon waking up every day without fail these last 2 weeks

my main question out of this one is has anyone else with neck tightness felt the same - as if the tightness & muscle spasming has been a constant, and / or if in turn it’s felt like a mass in your neck? and has anything worked for you such as physical therapy, exercises, etc?

and obviously anything else such as advice / etc related to other things brought up in this post are more than welcome !!

thanks so much in advance !! 🙂
